text: We study a linear rotor in a bosonic bath within the angulon formalism. Our
focus is on systems where isotropic or anisotropic impurity-boson interactions
support a shallow bound state. To study the fate of the angulon in the vicinity
of bound-state formation, we formulate a beyond-linear-coupling angulon Hamiltonian.
First, we use it to study attractive, spherically symmetric impurity-boson interactions
for which the linear rotor can be mapped onto a static impurity. The well-known
polaron formalism provides an adequate description in this limit. Second, we consider
anisotropic potentials, and show that the presence of a shallow bound state with
pronounced anisotropic character leads to a many-body instability that washes
out the angulon dynamics.

text: Die Quantenrotation ist ein spannendes Phänomen, das in vielen verschiedenen
Systemen auftritt, von Molekülen und Atomen bis hin zu subatomaren Teilchen wie
Neutronen und Protonen. Durch den Einsatz von starken Laserpulsen ist es möglich,
die mathematisch anspruchsvolle Topologie der Rotation von Molekülen aufzudecken
und topologisch geschützte Zustände zu erzeugen, die unerwartetes Verhalten zeigen.
Diese Entdeckungen könnten Auswirkungen auf die Molekülphysik und physikalische
Chemie haben und die Entwicklung neuer Technologien ermöglichen. Die Verbindung
von Quantenrotation und Topologie stellt ein aufregendes, interdisziplinäres Forschungsfeld
dar und bietet neue Wege zur Kontrolle und Nutzung von quantenmechanischen Phänomenen.

text: The impulsive limit (the “sudden approximation”) has been widely employed
to describe the interaction between molecules and short, far-off-resonant laser
pulses. This approximation assumes that the timescale of the laser-molecule interaction
is significantly shorter than the internal rotational period of the molecule,
resulting in the rotational motion being instantaneously “frozen” during the interaction.
This simplified description of the laser-molecule interaction is incorporated
in various theoretical models predicting rotational dynamics of molecules driven
by short laser pulses. In this theoretical work, we develop an effective theory
for ultrashort laser pulses by examining the full time-evolution operator and
solving the time-dependent Schrödinger equation at the operator level. Our findings
reveal a critical angular momentum, lcrit, at which the impulsive limit breaks
down. In other words, the validity of the sudden approximation depends not only
on the pulse duration but also on its intensity, since the latter determines how
many angular momentum states are populated. We explore both ultrashort multicycle
(Gaussian) pulses and the somewhat less studied half-cycle pulses, which produce
distinct effective potentials. We discuss the limitations of the impulsive limit
and propose a method that rescales the effective matrix elements, enabling an
improved and more accurate description of laser-molecule interactions.

text: Brownian motion of a mobile impurity in a bath is affected by spin-orbit coupling
(SOC). Here, we discuss a Caldeira-Leggett-type model that can be used to propose
and interpret quantum simulators of this problem in cold Bose gases. First, we
derive a master equation that describes the model and explore it in a one-dimensional
(1D) setting. To validate the standard assumptions needed for our derivation,
we analyze available experimental data without SOC; as a byproduct, this analysis
suggests that the quench dynamics of the impurity is beyond the 1D Bose-polaron
approach at temperatures currently accessible in a cold-atom laboratory—motion
of the impurity is mainly driven by dissipation. For systems with SOC, we demonstrate
that 1D spin-orbit coupling can be gauged out even in the presence of dissipation—the
information about SOC is incorporated in the initial conditions. Observables sensitive
to this information (such as spin densities) can be used to study formation of
steady spin polarization domains during quench dynamics.

text: A rotating organic cation and a dynamically disordered soft inorganic cage
are the hallmark features of organic-inorganic lead-halide perovskites. Understanding
the interplay between these two subsystems is a challenging problem, but it is
this coupling that is widely conjectured to be responsible for the unique behavior
of photocarriers in these materials. In this work, we use the fact that the polarizability
of the organic cation strongly depends on the ambient electrostatic environment
to put the molecule forward as a sensitive probe of the local crystal fields inside
the lattice cell. We measure the average polarizability of the C/N–H bond stretching
mode by means of infrared spectroscopy, which allows us to deduce the character
of the motion of the cation molecule, find the magnitude of the local crystal
field, and place an estimate on the strength of the hydrogen bond between the
hydrogen and halide atoms. Our results pave the way for understanding electric
fields in lead-halide perovskites using infrared bond spectroscopy.

text: 'Lead halide perovskites enjoy a number of remarkable optoelectronic properties.
To explain their origin, it is necessary to study how electromagnetic fields interact
with these systems. We address this problem here by studying two classical quantities:
Faraday rotation and the complex refractive index in a paradigmatic perovskite
CH3NH3PbBr3 in a broad wavelength range. We find that the minimal coupling of
electromagnetic fields to the k⋅p Hamiltonian is insufficient to describe the
observed data even on the qualitative level. To amend this, we demonstrate that
there exists a relevant atomic-level coupling between electromagnetic fields and
the spin degree of freedom. This spin-electric coupling allows for quantitative
description of a number of previous as well as present experimental data. In particular,
we use it here to show that the Faraday effect in lead halide perovskites is dominated
by the Zeeman splitting of the energy levels and has a substantial beyond-Becquerel
contribution. Finally, we present general symmetry-based phenomenological arguments
that in the low-energy limit our effective model includes all basis coupling terms
to the electromagnetic field in the linear order.'

text: 'We use general symmetry-based arguments to construct an effective model suitable
for studying optical properties of lead halide perovskites. To build the model,
we identify an atomic-level interaction between electromagnetic fields and the
spin degree of freedom that should be added to a minimally coupled k⋅p Hamiltonian.
As a first application, we study two basic optical characteristics of the material:
the Verdet constant and the refractive index. Beyond these linear characteristics
of the material, the model is suitable for calculating nonlinear effects such
as the third-order optical susceptibility. Analysis of this quantity shows that
the geometrical properties of the spin-electric term imply isotropic optical response
of the system, and that optical anisotropy of lead halide perovskites is a manifestation
of hopping of charge carriers. To illustrate this, we discuss third-harmonic generation.'

text: We show that the simplest of existing molecules—closed-shell diatomics not
interacting with one another—host topological charges when driven by periodic
far-off-resonant laser pulses. A periodically kicked molecular rotor can be mapped
onto a “crystalline” lattice in angular momentum space. This allows us to define
quasimomenta and the band structure in the Floquet representation, by analogy
with the Bloch waves of solid-state physics. Applying laser pulses spaced by 1/3
of the molecular rotational period creates a lattice with three atoms per unit
cell with staggered hopping. Within the synthetic dimension of the laser strength,
we discover Dirac cones with topological charges. These Dirac cones, topologically
protected by reflection and time-reversal symmetry, are reminiscent of (although
not equivalent to) that seen in graphene. They—and the corresponding edge states—are
broadly tunable by adjusting the laser strength and can be observed in present-day
experiments by measuring molecular alignment and populations of rotational levels.
This paves the way to study controllable topological physics in gas-phase experiments
with small molecules as well as to classify dynamical molecular states by their
topological invariants.

text: The angulon, a quasiparticle formed by a quantum rotor dressed by the excitations
of a many-body bath, can be used to describe an impurity rotating in a fluid or
solid environment. Here, we propose a coherent state ansatz in the co-rotating
frame, which provides a comprehensive theoretical description of angulons. We
reveal the quasiparticle properties, such as energies, quasiparticle weights,
and spectral functions, and show that our ansatz yields a persistent decrease
in the impurity’s rotational constant due to many-body dressing, which is consistent
with experimental observations. From our study, a picture of the angulon emerges
as an effective spin interacting with a magnetic field that is self-consistently
generated by the molecule’s rotation. Moreover, we discuss rotational spectroscopy,
which focuses on the response of rotating molecules to a laser perturbation in
the linear response regime. Importantly, we take into account initial-state interactions
that have been neglected in prior studies and reveal their impact on the excitation
spectrum. To examine the angulon instability regime, we use a single-excitation
ansatz and obtain results consistent with experiments, in which a broadening of
spectral lines is observed while phonon wings remain highly suppressed due to
initial-state interactions.

text: We study the impact of finite-range physics on the zero-range-model analysis
of three-body recombination in ultracold atoms. We find that temperature dependence
of the zero-range parameters can vary from one set of measurements to another
as it may be driven by the distribution of error bars in the experiment, and not
by the underlying three-body physics. To study finite-temperature effects in three-body
recombination beyond the zero-range physics, we introduce and examine a finite-range
model based upon a hyperspherical formalism. The systematic error discussed in
this Letter may provide a significant contribution to the error bars of measured
three-body parameters.

text: We present a low-scaling diagrammatic Monte Carlo approach to molecular correlation
energies. Using combinatorial graph theory to encode many-body Hugenholtz diagrams,
we sample the Møller-Plesset (MPn) perturbation series, obtaining accurate correlation
energies up to n=5, with quadratic scaling in the number of basis functions. Our
technique reduces the computational complexity of the molecular many-fermion correlation
problem, opening up the possibility of low-scaling, accurate stochastic computations
for a wide class of many-body systems described by Hugenholtz diagrams.

text: We demonstrate the possibility of a coupling between the magnetization direction
of a ferromagnet and the tilting angle of adsorbed achiral molecules. To illustrate
the mechanism of the coupling, we analyze a minimal Stoner model that includes
Rashba spin–orbit coupling due to the electric field on the surface of the ferromagnet.
The proposed mechanism allows us to study magnetic anisotropy of the system with
an extended Stoner–Wohlfarth model and argue that adsorbed achiral molecules can
change magnetocrystalline anisotropy of the substrate. Our research aims to motivate
further experimental studies of the current-free chirality induced spin selectivity
effect involving both enantiomers.

text: 'Traditionally, nuclear spin is not considered to affect biological processes.
Recently, this has changed as isotopic fractionation that deviates from classical
mass dependence was reported both in vitro and in vivo. In these cases, the isotopic
effect correlates with the nuclear magnetic spin. Here, we show nuclear spin effects
using stable oxygen isotopes (16O, 17O, and 18O) in two separate setups: an artificial
dioxygen production system and biological aquaporin channels in cells. We observe
that oxygen dynamics in chiral environments (in particular its transport) depend
on nuclear spin, suggesting future applications for controlled isotope separation
to be used, for instance, in NMR. To demonstrate the mechanism behind our findings,
we formulate theoretical models based on a nuclear-spin-enhanced switch between
electronic spin states. Accounting for the role of nuclear spin in biology can
provide insights into the role of quantum effects in living systems and help inspire
the development of future biotechnology solutions.'

text: We present a minimal model of ferroelectric large polarons, which are suggested
as one of the mechanisms responsible for the unique charge transport properties
of hybrid perovskites. We demonstrate that short-ranged charge–rotor interactions
lead to long-range ferroelectric ordering of rotors, which strongly affects the
carrier mobility. In the nonperturbative regime, where our theory cannot be reduced
to any of the earlier models, we reveal that the polaron is characterized by large
coherence length and a roughly tenfold increase of the effective mass as compared
to the bare mass. These results are in good agreement with other theoretical predictions
for ferroelectric polarons. Our model establishes a general phenomenological framework
for ferroelectric polarons providing the starting point for future studies of
their role in the transport properties of hybrid organic-inorganic perovskites.

text: We demonstrate that a sodium dimer, Na2(13Σ+u), residing on the surface of
a helium nanodroplet, can be set into rotation by a nonresonant 1.0 ps infrared
laser pulse. The time-dependent degree of alignment measured, exhibits a periodic,
gradually decreasing structure that deviates qualitatively from that expected
for gas-phase dimers. Comparison to alignment dynamics calculated from the time-dependent
rotational Schrödinger equation shows that the deviation is due to the alignment
dependent interaction between the dimer and the droplet surface. This interaction
confines the dimer to the tangential plane of the droplet surface at the point
where it resides and is the reason that the observed alignment dynamics is also
well described by a 2D quantum rotor model.

text: We study an impurity with a resonance level whose position coincides with
the Fermi energy of the surrounding Fermi gas. An impurity causes a rapid variation
of the scattering phase shift for fermions at the Fermi surface, introducing a
new characteristic length scale into the problem. We investigate manifestations
of this length scale in the self-energy of the impurity and in the density of
the bath. Our calculations reveal a model-independent deformation of the density
of the Fermi gas, which is determined by the width of the resonance. To provide
a broader picture, we investigate time evolution of the density in quench dynamics,
and study the behavior of the system at finite temperatures. Finally, we briefly
discuss implications of our findings for the Fermi-polaron problem.

text: A critical overview of the theory of the chirality-induced spin selectivity
(CISS) effect, that is, phenomena in which the chirality of molecular species
imparts significant spin selectivity to various electron processes, is provided.
Based on discussions in a recently held workshop, and further work published since,
the status of CISS effects—in electron transmission, electron transport, and chemical
reactions—is reviewed. For each, a detailed discussion of the state-of-the-art
in theoretical understanding is provided and remaining challenges and research
opportunities are identified.

text: Rotational dynamics of D2 molecules inside helium nanodroplets is induced
by a moderately intense femtosecond pump pulse and measured as a function of time
by recording the yield of HeD+ ions, created through strong-field dissociative
ionization with a delayed femtosecond probe pulse. The yield oscillates with a
period of 185 fs, reflecting field-free rotational wave packet dynamics, and the
oscillation persists for more than 500 periods. Within the experimental uncertainty,
the rotational constant BHe of the in-droplet D2 molecule, determined by Fourier
analysis, is the same as Bgas for an isolated D2 molecule. Our observations show
that the D2 molecules inside helium nanodroplets essentially rotate as free D2
molecules.

text: 'We investigate the ground-state properties of weakly repulsive one-dimensional
bosons in the presence of an attractive zero-range impurity potential. First,
we derive mean-field solutions to the problem on a finite ring for the two asymptotic
cases: (i) all bosons are bound to the impurity and (ii) all bosons are in a scattering
state. Moreover, we derive the critical line that separates these regimes in the
parameter space. In the thermodynamic limit, this critical line determines the
maximum number of bosons that can be bound by the impurity potential, forming
an artificial atom. Second, we validate the mean-field results using the flow
equation approach and the multi-layer multi-configuration time-dependent Hartree
method for atomic mixtures. While beyond-mean-field effects destroy long-range
order in the Bose gas, the critical boson number is unaffected. Our findings are
important for understanding such artificial atoms in low-density Bose gases with
static and mobile impurities.'

text: Recently it became possible to study highly excited rotational states of molecules
in superfluid helium through nonadiabatic alignment experiments (Cherepanov et
al 2021 Phys. Rev. A 104 L061303). This calls for theoretical approaches that
go beyond explaining renormalized values of molecular spectroscopic constants,
which suffices when only the lowest few rotational states are involved. As the
first step in this direction, here we present a basic quantum mechanical model
describing highly excited rotational states of molecules in superfluid helium
nanodroplets. We show that a linear molecule immersed in a superfluid can be seen
as an effective symmetric top, similar to the rotational structure of radicals,
such as OH or NO, but with the angular momentum of the superfluid playing the
role of the electronic angular momentum in free molecules. The simple theory sheds
light onto what happens when the rotational angular momentum of the molecule increases
beyond the lowest excited states accessible by infrared spectroscopy. In addition,
the model allows to estimate the effective rotational and centrifugal distortion
constants for a broad range of species and to explain the crossover between light
and heavy molecules in superfluid 4He in terms of the many-body wavefunction structure.
Some of the above mentioned insights can be acquired by analyzing a simple 2 ×
2 matrix.

text: Methods inspired from machine learning have recently attracted great interest
in the computational study of quantum many-particle systems. So far, however,
it has proven challenging to deal with microscopic models in which the total number
of particles is not conserved. To address this issue, we propose a variant of
neural network states, which we term neural coherent states. Taking the Fröhlich
impurity model as a case study, we show that neural coherent states can learn
the ground state of nonadditive systems very well. In particular, we recover exact
diagonalization in all regimes tested and observe substantial improvement over
the standard coherent state estimates in the most challenging intermediate-coupling
regime. Our approach is generic and does not assume specific details of the system,
suggesting wide applications.

text: Recently it was shown that anyons on the two-sphere naturally arise from a
system of molecular impurities exchanging angular momentum with a many-particle
bath (Phys. Rev. Lett. 126, 015301 (2021)). Here we further advance this approach
and rigorously demonstrate that in the experimentally realized regime the lowest
spectrum of two linear molecules immersed in superfluid helium corresponds to
the spectrum of two anyons on the sphere. We develop the formalism within the
framework of the recently experimentally observed angulon quasiparticle

text: Studies on the experimental realization of two-dimensional anyons in terms
of quasiparticles have been restricted, so far, to only anyons on the plane. It
is known, however, that the geometry and topology of space can have significant
effects on quantum statistics for particles moving on it. Here, we have undertaken
the first step toward realizing the emerging fractional statistics for particles
restricted to move on the sphere instead of on the plane. We show that such a
model arises naturally in the context of quantum impurity problems. In particular,
we demonstrate a setup in which the lowest-energy spectrum of two linear bosonic
or fermionic molecules immersed in a quantum many-particle environment can coincide
with the anyonic spectrum on the sphere. This paves the way toward the experimental
realization of anyons on the sphere using molecular impurities. Furthermore, since
a change in the alignment of the molecules corresponds to the exchange of the
particles on the sphere, such a realization reveals a novel type of exclusion
principle for molecular impurities, which could also be of use as a powerful technique
to measure the statistics parameter. Finally, our approach opens up a simple numerical
route to investigate the spectra of many anyons on the sphere. Accordingly, we
present the spectrum of two anyons on the sphere in the presence of a Dirac monopole
field.

text: We study an effective one-dimensional quantum model that includes friction
and spin-orbit coupling (SOC), and show that the model exhibits spin polarization
when both terms are finite. Most important, strong spin polarization can be observed
even for moderate SOC, provided that the friction is strong. Our findings might
help to explain the pronounced effect of chirality on spin distribution and transport
in chiral molecules. In particular, our model implies static magnetic properties
of a chiral molecule, which lead to Shiba-like states when a molecule is placed
on a superconductor, in accordance with recent experimental data.

text: A few years ago, flow equations were introduced as a technique for calculating
the ground-state energies of cold Bose gases with and without impurities. In this
paper, we extend this approach to compute observables other than the energy. As
an example, we calculate the densities, and phase fluctuations of one-dimensional
Bose gases with one and two impurities. For a single mobile impurity, we use flow
equations to validate the mean-field results obtained upon the Lee-Low-Pines transformation.
We show that the mean-field approximation is accurate for all values of the boson-impurity
interaction strength as long as the phase coherence length is much larger than
the healing length of the condensate. For two static impurities, we calculate
impurity-impurity interactions induced by the Bose gas. We find that leading order
perturbation theory fails when boson-impurity interactions are stronger than boson-boson
interactions. The mean-field approximation reproduces the flow equation results
for all values of the boson-impurity interaction strength as long as boson-boson
interactions are weak.

text: We combine experimental and theoretical approaches to explore excited rotational
states of molecules embedded in helium nanodroplets using CS2 and I2 as examples.
Laser-induced nonadiabatic molecular alignment is employed to measure spectral
lines for rotational states extending beyond those initially populated at the
0.37 K droplet temperature. We construct a simple quantum-mechanical model, based
on a linear rotor coupled to a single-mode bosonic bath, to determine the rotational
energy structure in its entirety. The calculated and measured spectral lines are
in good agreement. We show that the effect of the surrounding superfluid on molecular
rotation can be rationalized by a single quantity, the angular momentum, transferred
from the molecule to the droplet.

text: Methods inspired from machine learning have recently attracted great interest
in the computational study of quantum many-particle systems. So far, however,
it has proven challenging to deal with microscopic models in which the total number
of particles is not conserved. To address this issue, we propose a new variant
of neural network states, which we term neural coherent states. Taking the Fröhlich
impurity model as a case study, we show that neural coherent states can learn
the ground state of non-additive systems very well. In particular, we observe
substantial improvement over the standard coherent state estimates in the most
challenging intermediate coupling regime. Our approach is generic and does not
assume specific details of the system, suggesting wide applications.

text: We investigate the effect of coupling between translational and internal degrees
of freedom of composite quantum particles on their localization in a random potential.
We show that entanglement between the two degrees of freedom weakens localization
due to the upper bound imposed on the inverse participation ratio by purity of
a quantum state. We perform numerical calculations for a two-particle system bound
by a harmonic force in a 1D disordered lattice and a rigid rotor in a 2D disordered
lattice. We illustrate that the coupling has a dramatic effect on localization
properties, even with a small number of internal states participating in quantum
dynamics.

text: We study a mobile quantum impurity, possessing internal rotational degrees
of freedom, confined to a ring in the presence of a many-particle bosonic bath.
By considering the recently introduced rotating polaron problem, we define the
Hamiltonian and examine the energy spectrum. The weak-coupling regime is studied
by means of a variational ansatz in the truncated Fock space. The corresponding
spectrum indicates that there emerges a coupling between the internal and orbital
angular momenta of the impurity as a consequence of the phonon exchange. We interpret
the coupling as a phonon-mediated spin-orbit coupling and quantify it by using
a correlation function between the internal and the orbital angular momentum operators.
The strong-coupling regime is investigated within the Pekar approach, and it is
shown that the correlation function of the ground state shows a kink at a critical
coupling, that is explained by a sharp transition from the noninteracting state
to the states that exhibit strong interaction with the surroundings. The results
might find applications in such fields as spintronics or topological insulators
where spin-orbit coupling is of crucial importance.

text: "Alignment of OCS, CS2, and I2 molecules embedded in helium nanodroplets is
measured as a function\r\nof time following rotational excitation by a nonresonant,
comparatively weak ps laser pulse. The distinct\r\npeaks in the power spectra,
obtained by Fourier analysis, are used to determine the rotational, B, and\r\ncentrifugal
distortion, D, constants. For OCS, B and D match the values known from IR spectroscopy.
For\r\nCS2 and I2, they are the first experimental results reported. The alignment
dynamics calculated from the\r\ngas-phase rotational Schrödinger equation, using
the experimental in-droplet B and D values, agree in\r\ndetail with the measurement
for all three molecules. The rotational spectroscopy technique for molecules in\r\nhelium
droplets introduced here should apply to a range of molecules and complexes."

text: Nature creates electrons with two values of the spin projection quantum number.
In certain applications, it is important to filter electrons with one spin projection
from the rest. Such filtering is not trivial, since spin-dependent interactions
are often weak, and cannot lead to any substantial effect. Here we propose an
efficient spin filter based upon scattering from a two-dimensional crystal, which
is made of aligned point magnets. The polarization of the outgoing electron flux
is controlled by the crystal, and reaches maximum at specific values of the parameters.
In our scheme, polarization increase is accompanied by higher reflectivity of
the crystal. High transmission is feasible in scattering from a quantum cavity
made of two crystals. Our findings can be used for studies of low-energy spin-dependent
scattering from two-dimensional ordered structures made of magnetic atoms or aligned
chiral molecules.

text: Organic materials are known to feature long spin-diffusion times, originating
in a generally small spin–orbit coupling observed in these systems. From that
perspective, chiral molecules acting as efficient spin selectors pose a puzzle
that attracted a lot of attention in recent years. Here, we revisit the physical
origins of chiral-induced spin selectivity (CISS) and propose a simple analytic
minimal model to describe it. The model treats a chiral molecule as an anisotropic
wire with molecular dipole moments aligned arbitrarily with respect to the wire’s
axes and is therefore quite general. Importantly, it shows that the helical structure
of the molecule is not necessary to observe CISS and other chiral nonhelical molecules
can also be considered as potential candidates for the CISS effect. We also show
that the suggested simple model captures the main characteristics of CISS observed
in the experiment, without the need for additional constraints employed in the
previous studies. The results pave the way for understanding other related physical
phenomena where the CISS effect plays an essential role.

text: Dipolar (or spatially indirect) excitons (IXs) in semiconductor double quantum
well (DQW) subjected to an electric field are neutral species with a dipole moment
oriented perpendicular to the DQW plane. Here, we theoretically study interactions
between IXs in stacked DQW bilayers, where the dipolar coupling can be either
attractive or repulsive depending on the relative positions of the particles.
By using microscopic band structure calculations to determine the electronic states
forming the excitons, we show that the attractive dipolar interaction between
stacked IXs deforms their electronic wave function, thereby increasing the inter-DQW
interaction energy and making the IX even more electrically polarizable. Many-particle
interaction effects are addressed by considering the coupling between a single
IX in one of the DQWs to a cloud of IXs in the other DQW, which is modeled either
as a closed-packed lattice or as a continuum IX fluid. We find that the lattice
model yields IX interlayer binding energies decreasing with increasing lattice
density. This behavior is due to the dominating role of the intra-DQW dipolar
repulsion, which prevents more than one exciton from entering the attractive region
of the inter-DQW coupling. Finally, both models shows that the single IX distorts
the distribution of IXs in the adjacent DQW, thus inducing the formation of an
IX dipolar polaron (dipolaron). While the interlayer binding energy reduces with
IX density for lattice dipolarons, the continuous polaron model predicts a nonmonotonous
dependence on density in semiquantitative agreement with a recent experimental
study [cf. Hubert et al., Phys. Rev. X 9, 021026 (2019)].

text: One of the hallmarks of quantum statistics, tightly entwined with the concept
of topological phases of matter, is the prediction of anyons. Although anyons
are predicted to be realized in certain fractional quantum Hall systems, they
have not yet been unambiguously detected in experiment. Here we introduce a simple
quantum impurity model, where bosonic or fermionic impurities turn into anyons
as a consequence of their interaction with the surrounding many-particle bath.
A cloud of phonons dresses each impurity in such a way that it effectively attaches
fluxes or vortices to it and thereby converts it into an Abelian anyon. The corresponding
quantum impurity model, first, provides a different approach to the numerical
solution of the many-anyon problem, along with a concrete perspective of anyons
as emergent quasiparticles built from composite bosons or fermions. More importantly,
the model paves the way toward realizing anyons using impurities in crystal lattices
as well as ultracold gases. In particular, we consider two heavy electrons interacting
with a two-dimensional lattice crystal in a magnetic field, and show that when
the impurity-bath system is rotated at the cyclotron frequency, impurities behave
as anyons as a consequence of the angular momentum exchange between the impurities
and the bath. A possible experimental realization is proposed by identifying the
statistics parameter in terms of the mean-square distance of the impurities and
the magnetization of the impurity-bath system, both of which are accessible to
experiment. Another proposed application is impurities immersed in a two-dimensional
weakly interacting Bose gas.

text: Inspired by the possibility to experimentally manipulate and enhance chemical
reactivity in helium nanodroplets, we investigate the effective interaction and
the resulting correlations between two diatomic molecules immersed in a bath of
bosons. By analogy with the bipolaron, we introduce the biangulon quasiparticle
describing two rotating molecules that align with respect to each other due to
the effective attractive interaction mediated by the excitations of the bath.
We study this system in different parameter regimes and apply several theoretical
approaches to describe its properties. Using a Born–Oppenheimer approximation,
we investigate the dependence of the effective intermolecular interaction on the
rotational state of the two molecules. In the strong-coupling regime, a product-state
ansatz shows that the molecules tend to have a strong alignment in the ground
state. To investigate the system in the weak-coupling regime, we apply a one-phonon
excitation variational ansatz, which allows us to access the energy spectrum.
In comparison to the angulon quasiparticle, the biangulon shows shifted angulon
instabilities and an additional spectral instability, where resonant angular momentum
transfer between the molecules and the bath takes place. These features are proposed
as an experimentally observable signature for the formation of the biangulon quasiparticle.
Finally, by using products of single angulon and bare impurity wave functions
as basis states, we introduce a diagonalization scheme that allows us to describe
the transition from two separated angulons to a biangulon as a function of the
distance between the two molecules.

text: Problems involving quantum impurities, in which one or a few particles are
interacting with a macroscopic environment, represent a pervasive paradigm, spanning
across atomic, molecular, and condensed-matter physics. In this paper we introduce
new variational approaches to quantum impurities and apply them to the Fröhlich
polaron–a quasiparticle formed out of an electron (or other point-like impurity)
in a polar medium, and to the angulon–a quasiparticle formed out of a rotating
molecule in a bosonic bath. We benchmark these approaches against established
theories, evaluating their accuracy as a function of the impurity-bath coupling.

text: In 1915, Einstein and de Haas and Barnett demonstrated that changing the magnetization
of a magnetic material results in mechanical rotation and vice versa. At the microscopic
level, this effect governs the transfer between electron spin and orbital angular
momentum, and lattice degrees of freedom, understanding which is key for molecular
magnets, nano-magneto-mechanics, spintronics, and ultrafast magnetism. Until now,
the timescales of electron-to-lattice angular momentum transfer remain unclear,
since modeling this process on a microscopic level requires the addition of an
infinite amount of quantum angular momenta. We show that this problem can be solved
by reformulating it in terms of the recently discovered angulon quasiparticles,
which results in a rotationally invariant quantum many-body theory. In particular,
we demonstrate that nonperturbative effects take place even if the electron-phonon
coupling is weak and give rise to angular momentum transfer on femtosecond timescales.

text: Dipolar coupling plays a fundamental role in the interaction between electrically
or magnetically polarized species such as magnetic atoms and dipolar molecules
in a gas or dipolar excitons in the solid state. Unlike Coulomb or contactlike
interactions found in many atomic, molecular, and condensed-matter systems, this
interaction is long-ranged and highly anisotropic, as it changes from repulsive
to attractive depending on the relative positions and orientation of the dipoles.
Because of this unique property, many exotic, symmetry-breaking collective states
have been recently predicted for cold dipolar gases, but only a few have been
experimentally detected and only in dilute atomic dipolar Bose-Einstein condensates.
Here, we report on the first observation of attractive dipolar coupling between
excitonic dipoles using a new design of stacked semiconductor bilayers. We show
that the presence of a dipolar exciton fluid in one bilayer modifies the spatial
distribution and increases the binding energy of excitonic dipoles in a vertically
remote layer. The binding energy changes are explained using a many-body polaron
model describing the deformation of the exciton cloud due to its interaction with
a remote dipolar exciton. The surprising nonmonotonic dependence on the cloud
density indicates the important role of dipolar correlations, which is unique
to dense, strongly interacting dipolar solid-state systems. Our concept provides
a route for the realization of dipolar lattices with strong anisotropic interactions
in semiconductor systems, which open the way for the observation of theoretically
predicted new and exotic collective phases, as well as for engineering and sensing
their collective excitations.

text: The angular momentum of molecules, or, equivalently, their rotation in three-dimensional
space, is ideally suited for quantum control. Molecular angular momentum is naturally
quantized, time evolution is governed by a well-known Hamiltonian with only a
few accurately known parameters, and transitions between rotational levels can
be driven by external fields from various parts of the electromagnetic spectrum.
Control over the rotational motion can be exerted in one-, two-, and many-body
scenarios, thereby allowing one to probe Anderson localization, target stereoselectivity
of bimolecular reactions, or encode quantum information to name just a few examples.
The corresponding approaches to quantum control are pursued within separate, and
typically disjoint, subfields of physics, including ultrafast science, cold collisions,
ultracold gases, quantum information science, and condensed-matter physics. It
is the purpose of this review to present the various control phenomena, which
all rely on the same underlying physics, within a unified framework. To this end,
recall the Hamiltonian for free rotations, assuming the rigid rotor approximation
to be valid, and summarize the different ways for a rotor to interact with external
electromagnetic fields. These interactions can be exploited for control—from achieving
alignment, orientation, or laser cooling in a one-body framework, steering bimolecular
collisions, or realizing a quantum computer or quantum simulator in the many-body
setting.

text: We demonstrate that identical impurities immersed in a two-dimensional many-particle
bath can be viewed as flux-tube-charged-particle composites described by fractional
statistics. In particular, we find that the bath manifests itself as an external
magnetic flux tube with respect to the impurities, and hence the time-reversal
symmetry is broken for the effective Hamiltonian describing the impurities. The
emerging flux tube acts as a statistical gauge field after a certain critical
coupling. This critical coupling corresponds to the intersection point between
the quasiparticle state and the phonon wing, where the angular momentum is transferred
from the impurity to the bath. This amounts to a novel configuration with emerging
anyons. The proposed setup paves the way to realizing anyons using electrons interacting
with superfluid helium or lattice phonons, as well as using atomic impurities
in ultracold gases.

text: We present an approach to interacting quantum many-body systems based on the
notion of quantum groups, also known as q-deformed Lie algebras. In particular,
we show that, if the symmetry of a free quantum particle corresponds to a Lie
group G, in the presence of a many-body environment this particle can be described
by a deformed group, Gq. Crucially, the single deformation parameter, q, contains
all the information about the many-particle interactions in the system. We exemplify
our approach by considering a quantum rotor interacting with a bath of bosons,
and demonstrate that extracting the value of q from closed-form solutions in the
perturbative regime allows one to predict the behavior of the system for arbitrary
values of the impurity-bath coupling strength, in good agreement with nonperturbative
calculations. Furthermore, the value of the deformation parameter allows one to
predict at which coupling strengths rotor-bath interactions result in a formation
of a stable quasiparticle. The approach based on quantum groups does not only
allow for a drastic simplification of impurity problems, but also provides valuable
insights into hidden symmetries of interacting many-particle systems.

text: We study a quantum impurity possessing both translational and internal rotational
degrees of freedom interacting with a bosonic bath. Such a system corresponds
to a “rotating polaron,” which can be used to model, e.g., a rotating molecule
immersed in an ultracold Bose gas or superfluid helium. We derive the Hamiltonian
of the rotating polaron and study its spectrum in the weak- and strong-coupling
regimes using a combination of variational, diagrammatic, and mean-field approaches.
We reveal how the coupling between linear and angular momenta affects stable quasiparticle
states, and demonstrate that internal rotation leads to an enhanced self-localization
in the translational degrees of freedom.

text: Recently it was shown that a molecule rotating in a quantum solvent can be
described in terms of the “angulon” quasiparticle [M. Lemeshko, Phys. Rev. Lett.
118, 095301 (2017)]. Here we extend the angulon theory to the case of molecules
possessing an additional spin-1/2 degree of freedom and study the behavior of
the system in the presence of a static magnetic field. We show that exchange of
angular momentum between the molecule and the solvent can be altered by the field,
even though the solvent itself is non-magnetic. In particular, we demonstrate
a possibility to control resonant emission of phonons with a given angular momentum
using a magnetic field.

text: We introduce a diagrammatic Monte Carlo approach to angular momentum properties
of quantum many-particle systems possessing a macroscopic number of degrees of
freedom. The treatment is based on a diagrammatic expansion that merges the usual
Feynman diagrams with the angular momentum diagrams known from atomic and nuclear
structure theory, thereby incorporating the non-Abelian algebra inherent to quantum
rotations. Our approach is applicable at arbitrary coupling, is free of systematic
errors and of finite-size effects, and naturally provides access to the impurity
Green function. We exemplify the technique by obtaining an all-coupling solution
of the angulon model; however, the method is quite general and can be applied
to a broad variety of systems in which particles exchange quantum angular momentum
with their many-body environment.

text: In several settings of physics and chemistry one has to deal with molecules
interacting with some kind of an external environment, be it a gas, a solution,
or a crystal surface. Understanding molecular processes in the presence of such
a many-particle bath is inherently challenging, and usually requires large-scale
numerical computations. Here, we present an alternative approach to the problem,
based on the notion of the angulon quasiparticle. We show that molecules rotating
inside superfluid helium nanodroplets and Bose–Einstein condensates form angulons,
and therefore can be described by straightforward solutions of a simple microscopic
Hamiltonian. Casting the problem in the language of angulons allows us not only
to greatly simplify it, but also to gain insights into the origins of the observed
phenomena and to make predictions for future experimental studies.

text: 'The existence of a self-localization transition in the polaron problem has
been under an active debate ever since Landau suggested it 83 years ago. Here
we reveal the self-localization transition for the rotational analogue of the
polaron -- the angulon quasiparticle. We show that, unlike for the polarons, self-localization
of angulons occurs at finite impurity-bath coupling already at the mean-field
level. The transition is accompanied by the spherical-symmetry breaking of the
angulon ground state and a discontinuity in the first derivative of the ground-state
energy. Moreover, the type of the symmetry breaking is dictated by the symmetry
of the microscopic impurity-bath interaction, which leads to a number of distinct
self-localized states. The predicted effects can potentially be addressed in experiments
on cold molecules trapped in superfluid helium droplets and ultracold quantum
gases, as well as on electronic excitations in solids and Bose-Einstein condensates. '

text: 'It is a common knowledge that an effective interaction of a quantum impurity
with an electromagnetic field can be screened by surrounding charge carriers,
whether mobile or static. Here we demonstrate that very strong, "anomalous" screening
can take place in the presence of a neutral, weakly polarizable environment, due
to an exchange of orbital angular momentum between the impurity and the bath.
Furthermore, we show that it is possible to generalize all phenomena related to
isolated impurities in an external field to the case when a many-body environment
is present, by casting the problem in terms of the angulon quasiparticle. As a
result, the relevant observables such as the effective Rabi frequency, geometric
phase, and impurity spatial alignment are straightforward to evaluate in terms
of a single parameter: the angular-momentum-dependent screening factor.'

text: Understanding the behavior of molecules interacting with superfluid helium
represents a formidable challenge and, in general, requires approaches relying
on large-scale numerical simulations. Here we demonstrate that experimental data
collected over the last 20 years provide evidence that molecules immersed in superfluid
helium form recently-predicted angulon quasiparticles [Phys. Rev. Lett. 114, 203001
(2015)]. Most importantly, casting the many-body problem in terms of angulons
amounts to a drastic simplification and yields effective molecular moments of
inertia as straightforward analytic solutions of a simple microscopic Hamiltonian.
The outcome of the angulon theory is in good agreement with experiment for a broad
range of molecular impurities, from heavy to medium-mass to light species. These
results pave the way to understanding molecular rotation in liquid and crystalline
phases in terms of the angulon quasiparticle.

text: 'Rotation of molecules embedded in He nanodroplets is explored by a combination
of fs laser-induced alignment experiments and angulon quasiparticle theory. We
demonstrate that at low fluence of the fs alignment pulse, the molecule and its
solvation shell can be set into coherent collective rotation lasting long enough
to form revivals. With increasing fluence, however, the revivals disappear --
instead, rotational dynamics as rapid as for an isolated molecule is observed
during the first few picoseconds. Classical calculations trace this phenomenon
to transient decoupling of the molecule from its He shell. Our results open novel
opportunities for studying non-equilibrium solute-solvent dynamics and quantum
thermalization. '

text: Recently it was shown that an impurity exchanging orbital angular momentum
with a surrounding bath can be described in terms of the angulon quasiparticle
[Phys. Rev. Lett. 118, 095301 (2017)]. The angulon consists of a quantum rotor
dressed by a many-particle field of boson excitations, and can be formed out of,
for example, a molecule or a nonspherical atom in superfluid helium, or out of
an electron coupled to lattice phonons or a Bose condensate. Here we develop an
approach to the angulon based on the path-integral formalism, which sets the ground
for a systematic, perturbative treatment of the angulon problem. The resulting
perturbation series can be interpreted in terms of Feynman diagrams, from which,
in turn, one can derive a set of diagrammatic rules. These rules extend the machinery
of the graphical theory of angular momentum - well known from theoretical atomic
spectroscopy - to the case where an environment with an infinite number of degrees
of freedom is present. In particular, we show that each diagram can be interpreted
as a 'skeleton', which enforces angular momentum conservation, dressed by an additional
many-body contribution. This connection between the angulon theory and the graphical
theory of angular momentum is particularly important as it allows to systematically
and substantially simplify the analytical representation of each diagram. In order
to exemplify the technique, we calculate the 1- and 2-loop contributions to the
angulon self-energy, the spectral function, and the quasiparticle weight. The
diagrammatic theory we develop paves the way to investigate next-to-leading order
quantities in a more compact way compared to the variational approaches.

text: The formation of vortices is usually considered to be the main mechanism of
angular momentum disposal in superfluids. Recently, it was predicted that a superfluid
can acquire angular momentum via an alternative, microscopic route -- namely,
through interaction with rotating impurities, forming so-called `angulon quasiparticles'
[Phys. Rev. Lett. 114, 203001 (2015)]. The angulon instabilities correspond to
transfer of a small number of angular momentum quanta from the impurity to the
superfluid, as opposed to vortex instabilities, where angular momentum is quantized
in units of ℏ per atom. Furthermore, since conventional impurities (such as molecules)
represent three-dimensional (3D) rotors, the angular momentum transferred is intrinsically
3D as well, as opposed to a merely planar rotation which is inherent to vortices.
Herein we show that the angulon theory can explain the anomalous broadening of
the spectroscopic lines observed for CH 3 and NH 3 molecules in superfluid
helium nanodroplets, thereby providing a fingerprint of the emerging angulon instabilities
in experiment.

text: Recently it was shown that molecules rotating in superfluid helium can be
described in terms of the angulon quasiparticles (Phys. Rev. Lett. 118, 095301
(2017)). Here we demonstrate that in the experimentally realized regime the angulon
can be seen as a point charge on a 2-sphere interacting with a gauge field of
a non-abelian magnetic monopole. Unlike in several other settings, the gauge fields
of the angulon problem emerge in the real coordinate space, as opposed to the
momentum space or some effective parameter space. Furthermore, we find a topological
transition associated with making the monopole abelian, which takes place in the
vicinity of the previously reported angulon instabilities. These results pave
the way for studying topological phenomena in experiments on molecules trapped
in superfluid helium nanodroplets, as well as on other realizations of orbital
impurity problems.

text: 'Iodine (I 2 ) molecules embedded in He nanodroplets are aligned by a 160
ps long laser pulse. The highest degree of alignment, occurring at the peak of
the pulse and quantified by ⟨cos 2 θ 2D ⟩ , is measured as a function of the laser
intensity. The results are well described by ⟨cos 2 θ 2D ⟩ calculated for a gas
of isolated molecules each with an effective rotational constant of 0.6 times
the gas-phase value, and at a temperature of 0.4 K. Theoretical analysis using
the angulon quasiparticle to describe rotating molecules in superfluid helium
rationalizes why the alignment mechanism is similar to that of isolated molecules
with an effective rotational constant. A major advantage of molecules in He droplets
is that their 0.4 K temperature leads to stronger alignment than what can generally
be achieved for gas phase molecules -- here demonstrated by a direct comparison
of the droplet results to measurements on a ∼ 1 K supersonic beam of isolated
molecules. This point is further illustrated for more complex system by measurements
on 1,4-diiodobenzene and 1,4-dibromobenzene. For all three molecular species studied
the highest values of ⟨cos 2 θ 2D ⟩ achieved in He droplets exceed 0.96. '

text: In science, as in life, "surprises" can be adequately appreciated
only in the presence of a null model, what we expect a priori. In physics, theories
sometimes express the values of dimensionless physical constants as combinations
of mathematical constants like π or e. The inverse problem also arises, whereby
the measured value of a physical constant admits a "surprisingly" simple
approximation in terms of well-known mathematical constants. Can we estimate the
probability for this to be a mere coincidence, rather than an inkling of some
theory? We answer the question in the most naive form.

text: We study a polar molecule immersed in a superfluid environment, such as a
helium nanodroplet or a Bose–Einstein condensate, in the presence of a strong
electrostatic field. We show that coupling of the molecular pendular motion, induced
by the field, to the fluctuating bath leads to formation of pendulons—spherical
harmonic librators dressed by a field of many-particle excitations. We study the
behavior of the pendulon in a broad range of molecule–bath and molecule–field
interaction strengths, and reveal that its spectrum features a series of instabilities
which are absent in the field-free case of the angulon quasiparticle. Furthermore,
we show that an external field allows to fine-tune the positions of these instabilities
in the molecular rotational spectrum. This opens the door to detailed experimental
studies of redistribution of orbital angular momentum in many-particle systems.

Rev. Lett. 114, 203001 (2015)PRLTAO0031-900710.1103/PhysRevLett.114.203001] to
study the rotational spectrum of a cyanide molecular anion immersed into Bose-Einstein
condensates of rubidium and strontium. Based on ab initio potential energy surfaces,
we provide a detailed study of the rotational Lamb shift and many-body-induced
fine structure which arise due to dressing of molecular rotation by a field of
phonon excitations. We demonstrate that the magnitude of these effects is large
enough in order to be observed in modern experiments on cold molecular ions. Furthermore,
we introduce a novel method to construct pseudopotentials starting from the ab
initio potential energy surfaces, which provides a means to obtain effective coupling
constants for low-energy polaron models.

text: "The Fermi-Hubbard model is one of the key models of condensed matter physics,
which holds a\r\n\r\npotential for explaining the mystery of high-temperature
superconductivity. Recent progress in\r\n\r\nultracold atoms in optical lattices
has paved the way to studying the model’s phase diagram using\r\n\r\nthe tools
of quantum simulation, which emerged as a promising alternative to the numerical\r\n\r\ncalculations
plagued by the infamous sign problem. However, the temperatures achieved using\r\n\r\nelaborate
laser cooling protocols so far have been too high to show the appearance of\r\n\r\nantiferromagnetic (AF)
and superconducting quantum phases directly. In this work, we demonstrate\r\n\r\nthat
using the machinery of dissipative quantum state engineering, one can observe
the emergence of\r\n\r\nthe AF order in the Fermi-Hubbard model with fermions
in optical lattices. The core of the approach\r\n\r\nis to add incoherent laser
scattering in such a way that the AF state emerges as the dark state of\r\n\r\nthe
driven-dissipative dynamics. The proposed controlled dissipation channels described
in this work\r\n\r\nare straightforward to add to already existing experimental

text: 'During the past 70 years, the quantum theory of angular momentum has been
successfully applied to describing the properties of nuclei, atoms, and molecules,
and their interactions with each other as well as with external fields. Because
of the properties of quantum rotations, the angular-momentum algebra can be of
tremendous complexity even for a few interacting particles, such as valence electrons
of an atom, not to mention larger many-particle systems. In this work, we study
an example of the latter: A rotating quantum impurity coupled to a many-body bosonic
bath. In the regime of strong impurity-bath couplings, the problem involves the
addition of an infinite number of angular momenta, which renders it intractable
using currently available techniques. Here, we introduce a novel canonical transformation
that allows us to eliminate the complex angular-momentum algebra from such a class
of many-body problems. In addition, the transformation exposes the problem''s
constants of motion, and renders it solvable exactly in the limit of a slowly
rotating impurity. We exemplify the technique by showing that there exists a critical
rotational speed at which the impurity suddenly acquires one quantum of angular
momentum from the many-particle bath. Such an instability is accompanied by the
deformation of the phonon density in the frame rotating along with the impurity.'

text: Anisotropic dipole-dipole interactions between ultracold dipolar fermions
break the symmetry of the Fermi surface and thereby deform it. Here we demonstrate
that such a Fermi surface deformation induces a topological phase transition -
the so-called Lifshitz transition - in the regime accessible to present-day experiments.
We describe the impact of the Lifshitz transition on observable quantities such
as the Fermi surface topology, the density-density correlation function, and the
excitation spectrum of the system. The Lifshitz transition in ultracold atoms
can be controlled by tuning the dipole orientation and, in contrast to the transition
studied in crystalline solids, is completely interaction driven.

text: We use the dual boson approach to reveal the phase diagram of the Fermi-Hubbard
model with long-range dipole-dipole interactions. By using a large-scale finite-temperature
calculation on a 64×64 square lattice we demonstrate the existence of a novel
phase, possessing an "ultralong-range" order. The fingerprint of this
phase - the density correlation function - features a nontrivial behavior on a
scale of tens of lattice sites. We study the properties and the stability of the
ultralong-range-ordered phase, and show that it is accessible in modern experiments
with ultracold polar molecules and magnetic atoms.

text: "We investigate the occurrence of rotons in a quadrupolar Bose–Einstein condensate
confined to two dimensions. Depending on the particle density, the ratio of the
contact and quadrupole–quadrupole interactions, and the alignment of the quadrupole
moments with respect to the confinement plane, the dispersion relation features
two or four point-like roton minima or one ring-shaped minimum. We map out the
entire parameter space of the roton behavior and identify the instability regions.
We propose to observe the exotic rotons by monitoring the characteristic density
wave dynamics resulting from a short local perturbation, and discuss the possibilities
to detect the predicted effects in state-of-the-art experiments with ultracold
homonuclear molecules.\r\n"

text: We develop a microscopic theory describing a quantum impurity whose rotational
degree of freedom is coupled to a many-particle bath. We approach the problem
by introducing the concept of an “angulon”—a quantum rotor dressed by a quantum
field—and reveal its quasiparticle properties using a combination of variational
and diagrammatic techniques. Our theory predicts renormalization of the impurity
rotational structure, such as that observed in experiments with molecules in superfluid
helium droplets, in terms of a rotational Lamb shift induced by the many-particle
environment. Furthermore, we discover a rich many-body-induced fine structure,
emerging in rotational spectra due to a redistribution of angular momentum within
the quantum many-body system.

text: We propose a technique for engineering momentum-dependent dissipation in Bose-Einstein
condensates with non-local interactions. The scheme relies on the use of momentum-dependent
dark-states in close analogy to velocity-selective coherent population trapping.
During the short-time dissipative dynamics, the system is driven into a particular
finite-momentum phonon mode, which in real space corresponds to an ordered structure
with non-local density-density correlations. Dissipation-induced ordering can
be observed and studied in present-day experiments using cold atoms with dipole-dipole
or off-resonant Rydberg interactions. Due to its dissipative nature, the ordering
does not require artificial breaking of translational symmetry by an opticallattice
or harmonic trap. This opens up a perspective of direct cooling of quantum gases
into strongly-interacting phases.

text: 'We propose to detect quadrupole interactions of neutral ultracold atoms via
their induced mean-field shift. We consider a Mott insulator state of spin-polarized
atoms in a two-dimensional optical square lattice. The quadrupole moments of the
atoms are aligned by an external magnetic field. As the alignment angle is varied,
the mean-field shift shows a characteristic angular dependence, which constitutes
the defining signature of the quadrupole interaction. For the 3P2 states of Yb
and Sr atoms, we find a frequency shift of the order of tens of Hertz, which can
be realistically detected in experiment with current technology. We compare our
results to the mean-field shift of a spin-polarized quasi-two-dimensional Fermi
gas in continuum. '

text: Recently it has been shown that pairs of atoms can form metastable bonds due
to non-conservative forces induced by dissipation [Lemeshko&Weimer, Nature
Comm. 4, 2230 (2013)]. Here we study the dynamics of interaction-induced coherent
population trapping - the process responsible for the formation of dissipatively
bound molecules. We derive the effective dissipative potentials induced between
ultracold atoms by laser light, and study the time evolution of the scattering
states. We demonstrate that binding occurs on short timescales of ~10 microseconds,
even if the initial kinetic energy of the atoms significantly exceeds the depth
of the dissipative potential. Dissipatively-bound molecules with preordained bond
lengths and vibrational wavefunctions can be created and detected in current experiments
with ultracold atoms.

text: We introduce a new platform for quantum simulation of many-body systems based
on nonspherical atoms or molecules with zero dipole moments but possessing a significant
value of electric quadrupole moments. We consider a quadrupolar Fermi gas trapped
in a 2D square optical lattice, and show that the peculiar symmetry and broad
tunability of the quadrupole-quadrupole interaction results in a rich phase diagram
encompassing unconventional BCS and charge density wave phases, and opens up a
perspective to create a topological superfluid. Quadrupolar species, such as metastable
alkaline-earth atoms and homonuclear molecules, are stable against chemical reactions
and collapse and are readily available in experiment at high densities.

text: Magnetic impurities embedded in inert solids can exhibit long coherence times
and interact with one another via their intrinsic anisotropic dipolar interaction.
We argue that, as a consequence of these properties, disordered ensembles of magnetic
impurities provide an effective platform for realizing a controllable, tunable
version of the dipolar quantum spin glass seen in LiHoxY1-xF4. Specifically, we
propose and analyze a system composed of dysprosium atoms embedded in solid helium.
We describe the phase diagram of the system and discuss the realizability and
detectability of the quantum spin glass and antiglass phases.

text: The goal of the present article is to review the major developments that have
led to the current understanding of molecule-field interactions and experimental
methods for manipulating molecules with electromagnetic fields. Molecule-field
interactions are at the core of several, seemingly distinct areas of molecular
physics. This is reflected in the organisation of this article, which includes
sections on field control of molecular beams, external field traps for cold molecules,
control of molecular orientation and molecular alignment, manipulation of molecules
by non-conservative forces, ultracold molecules and ultracold chemistry, controlled
many-body phenomena, entanglement of molecules and dipole arrays, and stability
of molecular systems in high-frequency super-intense laser fields. The article
contains 852 references.

text: The formation of molecules and supramolecular structures results from bonding
by conservative forces acting among electrons and nuclei and giving rise to equilibrium
configurations defined by minima of the interaction potential. Here we show that
bonding can also occur by the non-conservative forces responsible for interaction-induced
coherent population trapping. The bound state arises in a dissipative process
and manifests itself as a stationary state at a preordained interatomic distance.
Remarkably, such a dissipative bonding is present even when the interactions among
the atoms are purely repulsive. The dissipative bound states can be created and
studied spectroscopically in present-day experiments with ultracold atoms or molecules
and can potentially serve for cooling strongly interacting quantum gases.

text: We show that the electric dipole-dipole interaction between a pair of polar
molecules undergoes an all-out transformation when superimposed by a far-off-resonant
optical field. The combined interaction potential becomes tunable by variation
of wavelength, polarisation and intensity of the optical field and its dependence
on the intermolecular separation exhibits a crossover from an inverse-power to
an oscillating behaviour. The ability thereby offered to control molecular interactions
opens up avenues toward the creation and manipulation of novel phases of ultracold
polar gases among whose characteristics is a long-range entanglement of the dipoles'
mutual orientation. We devised an accurate analytic model of such optical-field-dressed
dipole-dipole interaction potentials, which enables a straightforward access to
the optical-field parameters required for the design of intermolecular interactions
in the laboratory.

text: We study the growth dynamics of ordered structures of strongly interacting
polar molecules in optical lattices. Using a dipole blockade of microwave excitations,
we map the system onto an interacting spin-1/2 model possessing ground states
with crystalline order, and describe a way to prepare these states by nonadiabatically
driving the transitions between molecular rotational levels. The proposed technique
bypasses the need to cross a phase transition and allows for the creation of ordered
domains of considerably larger size compared to approaches relying on adiabatic
preparation.

text: We propose a method for sensitive parallel detection of low-frequency electromagnetic
fields based on the fine structure interactions in paramagnetic polar molecules.
Compared to the recently implemented scheme employing ultracold 87Rb atoms by
Böhi, the technique based on molecules offers a 100-fold higher sensitivity, the
possibility to measure both the electric and magnetic field components, and a
probe of a wide range of frequencies from the dc limit to the THz regime.

text: A (diatomic) shape resonance is a metastable state of a pair of colliding
atoms quasi-bound by the centrifugal barrier imposed by the angular momentum involved
in the collision. The temporary trapping of the atoms' scattering wavefunction
corresponds to an enhanced atom pair density at low interatomic separations. This
leads to larger overlap of the wavefunctions involved in a molecule formation
process such as photoassociation, rendering the process more efficient. However,
for an ensemble of atoms, the atom pair density will only be enhanced if the energy
of the resonance comes close to the temperature of the atomic ensemble. Herein
we explore the possibility of controlling the energy of a shape resonance by shifting
it toward the temperature of atoms confined in a trap. The shifts are imparted
by the interaction of non-resonant light with the anisotropic polarizability of
the atom pair, which affects both the centrifugal barrier and the pair's rotational
and vibrational levels. We find that at laser intensities of up to 5×109 W/cm2
the pair density is increased by one order of magnitude for 87Rb atoms at 100μK
and by two orders of magnitude for 88Sr atoms at 20μK.

text: We made use of supersymmetric (SUSY) quantum mechanics to find the condition
under which the Stark effect problem for a polar and polarizable closed-shell
diatomic molecule subjected to collinear electrostatic and nonresonant radiative
fields becomes exactly solvable. The condition Δω = ω2/4(m+1)2 connects values
of the dimensionless parameters ω and Δω that characterize the strengths of the
permanent and induced dipole interactions of the molecule with the respective
fields. The exact solutions are obtained for the \J̃ = m, m; ω, Δω) family of
'stretched' states. The field-free and strong-field limits of the combined-fields
problem were found to exhibit supersymmetry and shape invariance, which is indeed
the reason why they are analytically solvable. By making use of the analytic form
of the \J̃ = m,m; ω, Δω) wavefunctions, we obtained simple formulae for the expectation
values of the space-fixed electric dipole moment, the alignment cosine and the
angular momentum squared, and derived a 'sum rule' that combines the above expectation
values into a formula for the eigenenergy. The analytic expressions for the characteristics
of the strongly oriented and aligned states provide direct access to the values
of the interaction parameters required for creating such states in the laboratory.

text: By invoking supersymmetry, we found a condition under which the Stark-effect
problem for a polar and polarizable molecule subject to nonresonant electric fields
becomes exactly solvable for the family of stretched states. The analytic expressions

The method also allows the construction of families of isospectral potentials,
realizable with combined fields.

text: We show that dressing polar molecules with a far-off-resonant optical field
leads to new types of intermolecular potentials, which undergo a crossover from
the inverse power to oscillating behavior depending on the intermolecular distance,
and whose parameters can be tuned by varying the laser intensity and wavelength.
We present analytic expressions for the potential energy surfaces, thereby providing
direct access to the parameters of an optical field required to design intermolecular
interactions experimentally.

text: We develop an analytic model of vector correlations in rotationally inelastic
atom-diatom collisions and test it against the much examined Ar-NO (X2Π) system.
Based on the Fraunhofer scattering of matter waves, the model furnishes complex
scattering amplitudes needed to evaluate the polarization moments characterizing
the quantum stereodynamics. The analytic polarization moments are found to be
in an excellent agreement with experimental results and with close-coupling calculations
available at thermal energies. The model reveals that the stereodynamics is governed
by diffraction from the repulsive core of the Ar-NO potential, which can be characterized
by a single Legendre moment.

text: We evaluate the shifts imparted to vibrational and rotational levels of a
linear molecule by a nonresonant laser field at intensities of up to 10 12 W/cm2.
Both types of shift are found to be either positive or negative, depending on
the initial rotational state acted upon by the field. An adiabatic field-molecule
interaction imparts a rotational energy shift which is negative and exceeds the
concomitant positive vibrational shift by a few orders of magnitude. The rovibrational
states are thus pushed downward in such a field. A nonresonant pulsed laser field
that interacts nonadiabatically with the molecule is found to impart rotational
and vibrational shifts of the same order of magnitude. The nonadiabatic energy
transfer occurs most readily at a pulse duration which amounts to about a tenth
of the molecule's rotational period and vanishes when the sudden regime is attained
for shorter pulses. We applied our treatment to the much-studied 87Rb2 molecule
in the last bound vibrational levels of its lowest singlet and triplet electronic
states. Our calculations indicate that 15 and 1.5 ns laser pulses of an intensity
in excess of 5 × 109 W/cm2 are capable of dissociating the molecule due to the
vibrational shift. Lesser shifts can be used to fine-tune the rovibrational levels
and thereby affect collisional resonances by the nonresonant light. The energy
shifts due to laser intensities of 109 W/cm2 may be discernible spectroscopically,
with a 10 MHz resolution.

text: 'Following upon our recent work on vector correlations in the Ar-NO collisions
[Lemeshko and Friedrich, Phys. Chem. Chem. Phys. 12, 1038 (2010)], we compare
model results with close-coupling calculations for a range of channels and collision
energies for the He-NO system. The striking agreement between the model and exact
polarization moments indicates that the stereodynamics of rotationally inelastic
atom-molecule collisions at thermal energies is governed by diffraction of matter
waves from a two-dimensional repulsive core of the atom-molecule potential. Furthermore,
the model polarization moments characterizing the He-NO, He- O2, He-OH, and He-CaH
stereodynamics are found to coalesce into a single, distinctive pattern, which
can serve as a "fingerprint" to identify diffraction-driven stereodynamics
in future work. '

text: We present an analytic model of the refractive index for matter waves propagating
through atomic or molecular gases. The model, which combines the Wentzel-Kramers-Brillouin
(WKB) treatment of the long-range attraction with the Fraunhofer model treatment
of the short-range repulsion, furnishes a refractive index in compelling agreement
with recent experiments of Jacquey [Phys. Rev. Lett.PRLTAO0031-900710.1103/PhysRevLett.98.240405
98, 240405 (2007)] on Li atom matter waves passing through dilute noble gases.
We show that the diffractive contribution, which arises from scattering by a two-dimensional
"hard core" of the potential, is essential for obtaining a correct imaginary
part of the refractive index.

text: The local atomic structure of PbTiO3, BaTiO3, and KNbO3 perovskite-type crystals
and K x Na1 − x NbO3 solid solutions in different phases is investigated using
the angular dependence of the pre-edge structure of the Ti and Nb K X-ray absorption
spectra and the EXAFS data. In noncubic phases, a considerable deviation of the
local structure from the structure determined from diffraction data is observed
only for the tetragonal phase of the BaTiO3 crystal. It is revealed that, in the
cubic phase of niobates, the niobium atoms are characterized by significant displacements
from the centrosymmetric positions along the threefold axes, so that they are
close in the magnitude and the direction to the displacements in the low-temperatures
rhombohedral phases.

text: Relying on the quantization rule of Raab and Friedrich [Phys. Rev. A (2009)
in press], we derive simple and accurate formulae for the number of rotational
states supported by a weakly bound vibrational level of a diatomic molecular ion.
We also provide analytic estimates of the rotational constants of any such levels
up to threshold for dissociation and obtain a criterion for determining whether
a given weakly bound vibrational level is rotationless. The results depend solely
on the long-range part of the molecular potential.

text: We investigate the effects of a magnetic field on the dynamics of rotationally
inelastic collisions of open-shell molecules (Σ2, Σ3, and Π2) with closed-shell
atoms. Our treatment makes use of the Fraunhofer model of matter wave scattering
and its recent extension to collisions in electric [M. Lemeshko and B. Friedrich,
J. Chem. Phys. 129, 024301 (2008)] and radiative fields [M. Lemeshko and B. Friedrich,
Int. J. Mass. Spec. 280, 19 (2009)]. A magnetic field aligns the molecule in the
space-fixed frame and thereby alters the effective shape of the diffraction target.
This significantly affects the differential and integral scattering cross sections.
We exemplify our treatment by evaluating the magnetic-field-dependent scattering
characteristics of the He-CaH (XΣ+2), He-O2 (XΣ–3), and He-OH (XΠΩ2) systems at
thermal collision energies. Since the cross sections can be obtained for different
orientations of the magnetic field with respect to the relative velocity vector,
the model also offers predictions about the frontal-versus-lateral steric asymmetry
of the collisions. The steric asymmetry is found to be almost negligible for the
He-OH system, weak for the He-CaH collisions, and strong for the He-O2. While
odd ΔM transitions dominate the He-OH [J=3/2,f→J′,e/f] integral cross sections
in a magnetic field parallel to the relative velocity vector, even ΔM transitions
prevail in the case of the He-CaH (X2Σ+) and He-O2 (XΣ−3) collision systems. For
the latter system, the magnetic field opens inelastic channels that are closed
in the absence of the field. These involve the transitions N=1,J=0→N′, J′ with
J′=N′.

text: We examine the effects of a linearly polarized nonresonant radiative field
on the dynamics of rotationally inelastic Na+ + N2 collisions at eV collision
energies. Our treatment is based on the Fraunhofer model of matter wave scattering
and its recent extension to collisions in electric fields [M. Lemeshko, B. Friedrich,
J. Chem. Phys. 129 (2008) 024301]. The nonresonant radiative field changes the
effective shape of the target molecule by aligning it in the space-fixed frame.
This markedly alters the differential and integral scattering cross-sections.
As the cross-sections can be evaluated for a polarization of the radiative field
collinear or perpendicular to the relative velocity vector, the model also offers
predictions about steric asymmetry of the collisions.

text: We develop an analytic model of thermal state-to-state rotationally inelastic
collisions of asymmetric-top molecules with closed-shell atoms in electric fields
and apply it to the Ar-H2O collision system. The predicted cross sections as well
as the steric asymmetry of the collisions show at fields up to 150 kV/cm characteristic
field-dependent features which can be experimentally tested. Particularly suitable
candidates for such tests are the 000 → 220 and 101→ 221 channels, arising from
the relaxation of the field-free selection rules due to the hybridization of J
states by the field. Averaging over the M' product channels is found to largely
obliterate the orientation effects brought about by the field.

text: We show that weakly bound molecules can be probed by "shaking" in
a pulsed nonresonant laser field. The field introduces a centrifugal term which
expels the highest vibrational level from the potential that binds it. Our numerical
simulations applied to the Rb2 and KRb Feshbach molecules indicate that shaking
by feasible laser pulses can be used to accurately recover the square of the vibrational
wave function and, by inversion, also the long-range part of the molecular potential.

text: Despite the growing geological evidence that fluid boiling and vapour-liquid
separation affect the distribution of metals in magmatic-hydrothermal systems
significantly, there are few experimental data on the chemical status and partitioning
of metals in the vapour and liquid phases. Here we report on an in situ measurement,
using X-ray absorption fine structure (XAFS) spectroscopy, of antimony speciation
and partitioning in the system Sb2O3-H2O-NaCl-HCl at 400°C and pressures 270–300
bar corresponding to the vapour-liquid equilibrium. Experiments were performed
using a spectroscopic cell which allows simultaneous determination of the total
concentration and atomic environment of the absorbing element (Sb) in each phase.
Results show that quantitative vapour-brine separation of a supercritical aqueous
salt fluid can be achieved by a controlled decompression and monitoring the X-ray
absorbance of the fluid phase. Antimony concentrations in equilibrium with Sb2O3
(cubic, senarmontite) in the coexisting vapour and liquid phases and corresponding
SbIII vapour-liquid partitioning coefficients are in agreement with recent data
obtained using batch-reactor solubility techniques. The XAFS spectra analysis
shows that hydroxy-chloride complexes, probably Sb(OH)2Cl0, are dominant both
in the vapour and liquid phase in a salt-water system at acidic conditions. This
first in situ XAFS study of element fractionation between coexisting volatile
and dense phases opens new possibilities for systematic investigations of vapour-brine
and fluid-melt immiscibility phenomena, avoiding many experimental artifacts common
in less direct techniques.

text: 'We present an analytic model of thermal state-to-state rotationally inelastic
collisions of polar molecules in electric fields. The model is based on the Fraunhofer
scattering of matter waves and requires Legendre moments characterizing the “shape”
of the target in the body-fixed frame as its input. The electric field orients
the target in the space-fixed frame and thereby effects a striking alteration
of the dynamical observables: both the phase and amplitude of the oscillations
in the partial differential cross sections undergo characteristic field-dependent
changes that transgress into the partial integral cross sections. As the cross
sections can be evaluated for a field applied parallel or perpendicular to the
relative velocity, the model also offers predictions about steric asymmetry. We
exemplify the field-dependent quantum collision dynamics with the behavior of
the Ne–OCS(Σ1) and Ar–NO(Π2) systems. A comparison with the close-coupling calculations
available for the latter system [Chem. Phys. Lett.313, 491 (1999)] demonstrates
the model’s ability to qualitatively explain the field dependence of all the scattering
features observed.'

text: 'We present the physics of the quantum Zeno effect, whose gist is often expressed
by invoking the adage "a watched pot never boils". We review aspects
of the theoretical and experimental work done on the effect since its inception
in 1977, and mention some applications. We dedicate the article - with our very
best wishes - to Rudolf Zahradnik at the occasion of his great jubilee. Perhaps
Rudolf''s lasting youthfulness and freshness are due to that he himself had been
frequently observed throughout his life: until the political turn-around in 1989
by those who wished, by their surveillance, to prevent Rudolf from spoiling the
youth by his personal culture and his passion for science and things beautiful
and useful in general. This attempt had failed. Out of gratitude, the youth has
infected Rudolf with its youthfulness. Chronically. Since 1989, Rudolf has been
closely watched by the public at large. For the same traits of his as before,
but with the opposite goal and for the benefit of all generations. We relish keeping
him in sight...'

text: We use the x-ray absorption fine structure spectroscopy at Nb K edge to reveal
the local atomic structure of KxNa1−xNbO3 (PSN) solid solutions. The study is
performed over the temperature range 10–1023K for six different x values. We show
that only the combined analysis of extended x-ray absorption fine structure and
preedge fine structure provides complete and reliable information about the local
structure of NbO6 octahedra. Such extensive treatment of the experimental data
shows that the local structure of PSN could be described within the spherical
model proposed earlier as a hypothesis for perovskite-type ferroelectric zirconates.
We reveal that the Nb atoms are localized near their average positions on the
sphere surfaces for all temperatures and x values. With regard to previous results
we point out the features of microscopic structure common for PSN and perovskite-type
zirconates.

text: 'Local atomic structure of the piezoelectric ceramics KxNa 1-xNbO3 (x≤0.00,
0.05, 0.30, 0.40, 0.50 and 0.65) is studied in all phase regions (10 K-1023 K)
using Nb K-edge extended X-ray absorption fine-structure (EXAFS) spectroscopy.
We have shown the validity of a new spherical model for phase transitions on the
basis of both fitting of EXAFS signal in the R-space and differential EXAFS analysis.
Within this model the Nb atoms are located on the surfaces of small spheres of
constant radii surrounding centers of NbO6 octahedrons in all phases. The distribution
of the Nb atom on this surface changes during phase transitions. Besides, the
analysis of local structure reveals that the geometry of NbO6 octahedra does not
depend on the x value at each temperature, whereas the octahedra rotation angles
do. '

text: Predissociation of the N+2 C 2Σ+u(v') vibrational levels with v' ≥ 3 was observed
via dispersed C 2Σ+u → X 2Σ+g fluorescence in the spectral range of 165–208 nm
after resonant 1s−1π*(vr) excitation of N2 and its subsequent autoionization into
the N+2 C state. This range is dominated by lines in atomic nitrogen, by overlapped
C 2Σ+u(v') → X 2Σ+g(v'') vibrational band sequences with Δv = const and broad
unresolved band systems (D, (2))2Πg(v') → A2Πu(v'') in the N+2 molecular ion.
With very high fluorescence resolution of about 0.1 nm FWHM individual C 2Σ+u(v')
→ X 2Σ+g(v'') vibrational bands have been resolved. Calculation of the observed
fluorescence spectra by taking into account predissociation and molecular rotation
describes well the shape of both individual vibrational bands C 2Σ+u(v') → X 2Σ+g(v'')
and the whole band system.

text: 'Temperature dependent preedge and extended x-ray absorption fine structure
measurements at the Zr K edge for the perovskite-type zirconates Pb Zr0.515 Ti0.485
O3 (PZT), PbZr O3 (PZ), and BaZr O3 are performed. To carry out a more accurate
study of the weak reconstruction of the local atomic structure we employed a combination
of two techniques: (i) analysis of the preedge fine structure, and (ii) analysis
of the Fourier transform of the difference between χ (k) functions obtained at
different temperatures. A detailed investigation of local atomic structure in
the cubic phase for all the crystals is also performed. It is shown that neither
the displacive nor the order-disorder model can describe correctly the changes
of local atomic structure during phase transitions in PZ and PZT. A spherical
model describing the local atomic structure of perovskite-type crystals suffering
structural phase transitions is proposed.'

text: Fluorescence from fragments formed after the de-excitation of the N*2(1s−1π*)
resonance has been measured in the spectral range of 135–190 nm. This range is
dominated by lines in atomic nitrogen and lines formed by overlapping C2Σ+u(v')
→ X2Σ+g(v'') bands with Δv = const in the N+2 molecular ion which result from
the spectator Auger decays of the N*2(1s−1π*(vr)) resonances. Ab initio calculations
of the corresponding potential curves and transition probabilities showed that
the observed irregular intensity dependence of the C2Σ+u(v') → X2Σ+g(v'')(Δv =
const) fluorescence lines on the vibrational quantum number vr is due to transitions
between vibrational levels during the reaction N2(v0 = 0)→ N*2(1s−1π*(vr)) Longrightarrow
C2Σ+u(v') → X2Σ+g(v'').
