text: We study few-body bound states of charged particles subject to attractive
zero-range/short-range plus repulsive Coulomb interparticle forces. The characteristic
length scales of the system at zero energy are set by the Coulomb length scale
D and the Coulomb-modified effective range r eff. We study shallow bound states
of charged particles with D >> r eff and show that these systems obey universal
scaling laws different from neutral particles. An accurate description of these
states requires both the Coulomb-modified scattering length and the effective
range unless the Coulomb interaction is very weak (D -> ). Our findings are relevant
for bound states whose spatial extent is significantly larger than the range of
the attractive potential. These states enjoy universality – their character is
independent of the shape of the short-range potential.

text: We investigate the ground-state energy of a one-dimensional Fermi gas with
two bosonic impurities. We consider spinless fermions with no fermion-fermion
interactions. The fermion-impurity and impurity-impurity interactions are modeled
with Dirac delta functions. First, we study the case where impurity and fermion
have equal masses, and the impurity-impurity two-body interaction is identical
to the fermion-impurity interaction, such that the system is solvable with the
Bethe ansatz. For attractive interactions, we find that the energy of the impurity-impurity
subsystem is below the energy of the bound state that exists without the Fermi
gas. We interpret this as a manifestation of attractive boson-boson interactions
induced by the fermionic medium, and refer to the impurity-impurity subsystem
as an in-medium bound state. For repulsive interactions, we find no in-medium
bound states. Second, we construct an effective model to describe these interactions,
and compare its predictions to the exact solution. We use this effective model
to study nonintegrable systems with unequal masses and/or potentials. We discuss
parameter regimes for which impurity-impurity attraction induced by the Fermi
gas can lead to the formation of in-medium bound states made of bosons that repel
each other in the absence of the Fermi gas.

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: 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: It is shown that two fundamentally different phenomena, the bound states in
continuum and the spectral singularity (or time-reversed spectral singularity),
can occur simultaneously. This can be achieved in a rectangular core dielectric
waveguide with an embedded active (or absorbing) layer. In such a system a two-dimensional
bound state in a continuum is created in the plane of a waveguide cross section,
and it is emitted or absorbed along the waveguide core. The idea can be used for
experimental implementation of a laser or a coherent-perfect-absorber for a photonic
bound state that resides in a continuous spectrum.

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: 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: 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 analyze the theoretical derivation of the beyond-mean-field equation of
state for two-dimensional gas of dilute, ultracold alkali-metal atoms in the Bardeen–Cooper–Schrieffer
(BCS) to Bose–Einstein condensate (BEC) crossover. We show that at zero temperature
our theory — considering Gaussian fluctuations on top of the mean-field equation
of state — is in very good agreement with experimental data. Subsequently, we
investigate the superfluid density at finite temperature and its renormalization
due to the proliferation of vortex–antivortex pairs. By doing so, we determine
the Berezinskii–Kosterlitz–Thouless (BKT) critical temperature — at which the
renormalized superfluid density jumps to zero — as a function of the inter-atomic
potential strength. We find that the Nelson–Kosterlitz criterion overestimates
the BKT temperature with respect to the renormalization group equations, this
effect being particularly relevant in the intermediate regime of the crossover.

text: We investigate the quantum interference induced shifts between energetically
close states in highly charged ions, with the energy structure being observed
by laser spectroscopy. In this work, we focus on hyperfine states of lithiumlike
heavy-Z isotopes and quantify how much quantum interference changes the observed
transition frequencies. The process of photon excitation and subsequent photon
decay for the transition 2s→2p→2s is implemented with fully relativistic and full-multipole
frameworks, which are relevant for such relativistic atomic systems. We consider
the isotopes Pb79+207 and Bi80+209 due to experimental interest, as well as other
examples of isotopes with lower Z, namely Pr56+141 and Ho64+165. We conclude that
quantum interference can induce shifts up to 11% of the linewidth in the measurable
resonances of the considered isotopes, if interference between resonances is neglected.
The inclusion of relativity decreases the cross section by 35%, mainly due to
the complete retardation form of the electric dipole multipole. However, the contribution
of the next higher multipoles (e.g., magnetic quadrupole) to the cross section
is negligible. This makes the contribution of relativity and higher-order multipoles
to the quantum interference induced shifts a minor effect, even for heavy-Z elements.

text: We developed a method to calculate two-photon processes in quantum mechanics
that replaces the infinite summation over the intermediate states by a perturbation
expansion. This latter consists of a series of commutators that involve position,
momentum, and Hamiltonian quantum operators. We analyzed several single- and many-particle
cases for which a closed-form solution to the perturbation expansion exists, as
well as more complicated cases for which a solution is found by convergence. Throughout
the article, Rayleigh and Raman scattering are taken as examples of two-photon
processes. The present method provides a clear distinction between the Thomson
scattering, regarded as classical scattering, and quantum contributions. Such
a distinction lets us derive general results concerning light scattering. Finally,
possible extensions to the developed formalism are discussed.

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: '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: 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: '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: 'We investigate the effect of the electron-hole (e-h) symmetry breaking on
d-wave superconductivity induced by non-local effects of correlations in the generalized
Hubbard model. The symmetry breaking is introduced in a two-fold manner: by the
next-to-nearest neighbor hopping of electrons and by the charge-bond interaction
- the off-diagonal term of the Coulomb potential. Both terms lead to a pronounced
asymmetry of the superconducting order parameter. The next-to-nearest neighbor
hopping enhances superconductivity for h-doping, while diminishes it for e-doping.
The charge-bond interaction alone leads to the opposite effect and, additionally,
to the kinetic-energy gain upon condensation in the underdoped regime. With both
terms included, with similar amplitudes, the height of the superconducting dome
and the critical doping remain in favor of h-doping. The influence of the charge-bond
interaction on deviations from symmetry of the shape of the gap at the Fermi surface
in the momentum space is briefly discussed.'

text: The first hundred attoseconds of the electron dynamics during strong field
tunneling ionization are investigated. We quantify theoretically how the electron’s
classical trajectories in the continuum emerge from the tunneling process and
test the results with those achieved in parallel from attoclock measurements.
An especially high sensitivity on the tunneling barrier is accomplished here by
comparing the momentum distributions of two atomic species of slightly deviating
atomic potentials (argon and krypton) being ionized under absolutely identical
conditions with near-infrared laser pulses (1300 nm). The agreement between experiment
and theory provides clear evidence for a nonzero tunneling time delay and a nonvanishing
longitudinal momentum of the electron at the “tunnel exit.”
