text: We investigate a molecular quantum rotor in a two-dimensional Bose-Einstein
condensate. The focus is on studying the angulon quasiparticle concept in the
crossover from few- to many-body physics. To this end, we formulate the problem
in real space and solve it with a mean-field approach in the frame co-rotating
with the impurity. We show that the system starts to feature angulon characteristics
when the size of the bosonic cloud is large enough to screen the rotor. More importantly,
we demonstrate the departure from the angulon picture for large system sizes or
large angular momenta where the properties of the system are determined by collective
excitations of the Bose gas.

text: We demonstrate the formation of ferroelectric domain-wall polarons in a minimal
two-dimensional lattice model of electrons interacting with rotating dipoles.
Along the domain wall, the rotors polarize in opposite directions, causing the
electron to localize along a particular lattice direction. The rotor-electron
coupling is identified as the origin of a structural instability in the crystal
that leads to the domain-wall formation via a symmetry-breaking process. Our results
provide the first theoretical description of ferroelectric polarons, as discussed
in the context of soft semiconductors.

text: Alkali dimers, Ak2, located on the surface of a helium nanodroplet, are set
into rotation through the polarizability interaction with a nonresonant 1-ps-long
laser pulse. The time-dependent degree of alignment is recorded using femtosecond-probe-pulse-induced
Coulomb explosion into a pair of Ak+ fragment ions. The results, obtained for
Na2, K2, and Rb2 in both the ground state 11Σ+g and the lowest-lying triplet state
13Σ+u, exhibit distinct, periodic revivals with a gradually decreasing amplitude.
The dynamics differ from that expected for dimers had they behaved as free rotors.
Numerically, we solve the time-dependent rotational Schrödinger equation, including
an effective mean-field potential to describe the interaction between the dimer
and the droplet. The experimental and simulated alignment dynamics agree well
and their comparison enables us to determine the effective rotational constants
of the alkali dimers with the exception of Rb2(13Σ+u) that only exhibits a prompt
alignment peak but no subsequent revivals. For Na2(13Σ+u), K2(11Σ+g), K2(13Σ+u)
and Rb2(11Σ+g), the alignment dynamics are well-described by a 2D rotor model.
We ascribe this to a significant confinement of the internuclear axis of these
dimers, induced by the orientation-dependent droplet-dimer interaction, to the
tangential plane of their residence point on the droplet.

text: In standard quantum electrodynamics (QED), the so-called non-minimal (Pauli)
coupling is suppressed for elementary particles and has no physical implications.
Here, we show that the Pauli term naturally appears in a known family of Dirac
materials—the lead-halide perovskites, suggesting a novel playground for the study
of analog QED effects. We outline measurable manifestations of the Pauli term
in the phenomena pertaining to (i) relativistic corrections to bound states (ii)
the Klein paradox, and (iii) spin effects in scattering. In particular, we demonstrate
that (a) the binding energy of an electron in the vicinity of a positively charged
defect is noticeably decreased due to the polarizability of lead ions and the
appearance of a Darwin-like term, (b) strong spin-orbit coupling due to the Pauli
term affects the exciton states, and (c) scattering of an electron off an energy
barrier with broken mirror symmetry produces spin polarization in the outgoing
current. Our study adds to the understanding of quantum phenomena in lead-halide
perovskites and paves the way for tabletop simulations of analog Dirac-Pauli equations.

text: "Rotations constitute one of the fundamental symmetries in physics, characterized
by their intricate group structure and infinite dimensional representations. In
contrast to classical rotations, quantum mechanics unveils the SO(3) symmetry
group structure, manifesting in phenomena without classical counterparts, from
angular momentum quantization to non-trivial addition of angular momenta.\r\nWhile
most studies of topological physics have focused on two-band systems, the SO(3)
symmetry group of quantum rotors offers an inherently more complex platform with
unprecedented possibilities for exploring topological phenomena. Despite their
ubiquity in nature– from molecules to nanorotors– their potential for hosting
topological phases has remained largely unexamined.\r\nIn this thesis, we mainly
focus on periodically driven linear molecules as a prototype for studying topological
phenomena in quantum rotors. Recent technological advances in coherent control
of molecules, particularly through precisely shaped laser pulses, have made it
possible to investigate linear rotors in the context of topology. While planar
rotors have received some attention in recent years, threedimensional rotors–particularly
linear molecules–harbor substantially richer topological phenomena due to their
non-abelian nature and their additional angular degrees of freedom. We demonstrate
that these systems can host novel edge states and topological features fundamentally
impossible in planar systems.\r\nWe begin by establishing a theoretical bridge
between periodically kicked rotors and \"crystalline\" lattices in angular momentum
space. Using non-interacting linear molecules as our primary example, we show
how quantum interference and revival patterns lead to the possibility to simulate
band models with arbitrary number of bands N. While our framework applies to various
quantum rotors, including nanorotors and kicked Bose-Einstein condensates, linear\r\nmolecules
provide an ideal experimental platform due to their abovementioned precise controllability.\r\nThe
core of this work examines adiabatic dynamics of 3D quantum rotors, establishing
a geometric framework based on the Euler class to characterize its non-abelian
topology. The non-Hermitian nature of the system enables novel braiding behaviors
and topological transitions impossible in static systems, leading to an anomalous
Dirac string phase with edge states in each gap, even though the Berry phases
are all zero. These features can be directly observed through\r\nmolecular alignment
and rotational level populations.\r\nThese findings establish quantum rotors as
an alternative platform for studying multi-band topological physics, while suggesting
practical implementations for quantum computation where topological protection
could offer natural resilience against decoherence. The rich structure of three-dimensional
rotation groups, combined with the tunability of topological features through
driving parameters, makes this platform particularly valuable for exploring fundamental\r\nphysics
and developing quantum technologies."

text: 'Rotations are found in physics problems at all scales: from spatial motion
of celestial bodies, to transitions between quantum states of atoms and molecules.
Mathematically, they represent a fundamental class of transformations and symmetries.
Unlike spatial displacements, rotational transformations in three-dimensional
space are non-commutative: the result of applying a sequence of rotations depends
on the order of these operations. This feature makes the emergent physics that
involves rotations rather intricate, but instrumental for studies of highly-interconnected
many-body systems. In the presence of an environment, rotational properties of
an object change, due to the interaction with particles of the environment. Owing
to the complexity of this interaction, it can be engineered to exhibit certain
properties of interest. In this Thesis, we examine several scenarios of how the
rotational behavior of an impurity can be modified by interactions with its environment.'

text: We study a three-dimensional Gross-Pitaevskii equation that describes a static
impurity in a dipolar Bose-Einstein condensate. Our focus is on the interplay
between the shape of the impurity and the anisotropy of the medium manifested
in the energy and the density of the system. Without external confinement, properties
of the system are derived with basic analytical approaches. For a system in a
harmonic trap, the model is investigated numerically, using the split-step Crank-Nicolson
method. Our results demonstrate that the impurity self-energy is minimized when
its shape more closely aligns with the anisotropic character of the bath; in particular
a prolate deformed impurity aligned with the direction of the dipoles has the
smallest self-energy for a repulsive impurity. Our work complements studies of
impurities in Bose gases with zero-range interactions and paves the way for studies
of dipolar polarons with a Gross-Pitaevskii equation.

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: Coupling of orbital motion to a spin degree of freedom gives rise to various
transport phenomena in quantum systems that are beyond the standard paradigms
of classical physics. Here, we discuss features of spin-orbit dynamics that can
be visualized using a classical model with two coupled angular degrees of freedom.
Specifically, we demonstrate classical ‘spin’ filtering through our model and
show that the interplay between angular degrees of freedom and dissipation can
lead to asymmetric ‘spin’ transport.

text: Atom-based quantum simulators have had many successes in tackling challenging
quantum many-body problems, owing to the precise and dynamical control that they
provide over the systems' parameters. They are, however, often optimized to address
a specific type of problem. Here, we present the design and implementation of
a 6Li-based quantum gas platform that provides wide-ranging capabilities and is
able to address a variety of quantum many-body problems. Our two-chamber architecture
relies on a robust combination of gray molasses and optical transport from a laser-cooling
chamber to a glass cell with excellent optical access. There, we first create
unitary Fermi superfluids in a three-dimensional axially symmetric harmonic trap
and characterize them using in situ thermometry, reaching temperatures below 20
nK. This allows us to enter the deep superfluid regime with samples of extreme
diluteness, where the interparticle spacing is sufficiently large for direct single-atom
imaging. Second, we generate optical lattice potentials with triangular and honeycomb
geometry in which we study diffraction of molecular Bose-Einstein condensates,
and show how going beyond the Kapitza-Dirac regime allows us to unambiguously
distinguish between the two geometries. With the ability to probe quantum many-body
physics in both discrete and continuous space, and its suitability for bulk and
single-atom imaging, our setup represents an important step towards achieving
a wide-scope quantum simulator.

text: We perform a diagrammatic analysis of the energy of a mobile impurity immersed
in a strongly interacting two-component Fermi gas to second order in the impurity-bath
interaction. These corrections demonstrate divergent behavior in the limit of
large impurity momentum. We show the fundamental processes responsible for these
logarithmically divergent terms. We study the problem in the general case without
any assumptions regarding the fermion-fermion interactions in the bath. We show
that the divergent term can be summed up to all orders in the Fermi-Fermi interaction
and that the resulting expression is equivalent to the one obtained in the few-body
calculation. Finally, we provide a perturbative calculation to the second order
in the Fermi-Fermi interaction, and we show the diagrams responsible for these
terms.

text: We demonstrate the failure of the adiabatic Born-Oppenheimer approximation
to describe the ground state of a quantum impurity within an ultracold Fermi gas
despite substantial mass differences between the bath and impurity species. Increasing
repulsion leads to the appearance of nonadiabatic couplings between the fast bath
and slow impurity degrees of freedom, which reduce the parity symmetry of the
latter according to the pseudo Jahn-Teller effect. The presence of this mechanism
is associated to a conical intersection involving the impurity position and the
inverse of the interaction strength, which acts as a synthetic dimension. We elucidate
the presence of these effects via a detailed ground-state analysis involving the
comparison of ab initio fully correlated simulations with effective models. Our
study suggests ultracold atomic ensembles as potent emulators of complex molecular
phenomena.

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: 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: "We demonstrate that periodically driven quantum rotors provide a promising
and broadly applicable platform to implement multi-gap topological phases, where
groups of bands can acquire topological invariants due to non-Abelian braiding
of band degeneracies. By adiabatically varying the periodic kicks to the rotor
we find nodal-line braiding, which causes sign flips of topological charges of
band nodes and can prevent them from annihilating, indicated by non-zero values
of the %non-Abelian patch Euler class. In particular, we report\r\non the emergence
of an anomalous Dirac string phase arising in the strongly driven regime, a truly
out-of-equilibrium phase of the quantum rotor. This phase emanates from braiding
processes involving all (quasienergy) gaps and manifests itself with edge states
at zero angular momentum. Our results reveal direct applications in state-of-the-art
experiments of quantum rotors, such as linear molecules driven by periodic far-off-resonant
laser pulses or artificial\r\nquantum rotors in optical lattices, whose extensive
versatility offers precise modification and observation of novel non-Abelian topological
properties. "

text: We present a theory describing the interaction of structured light, such as
light carrying orbital angular momentum, with molecules. The light-matter interaction
Hamiltonian we derive is expressed through couplings between spherical gradients
of the electric field and the (transition) electric multipole moments of a particle
of any nontrivial rotation point group. Our model can therefore accommodate an
arbitrary complexity of the molecular and electric field structure, and it can
be straightforwardly extended to atoms or nanostructures. Applying this framework
to rovibrational spectroscopy of molecules, we uncover the general mechanism of
angular momentum exchange between the spin and orbital angular momenta of light,
molecular rotation, and its center-of-mass motion. We show that the nonzero vorticity
of Laguerre-Gaussian beams can strongly enhance certain rovibrational transitions
that are considered forbidden in the case of nonhelical light. We discuss the
experimental requirements for the observation of these forbidden transitions in
state-of-the-art spatially resolved spectroscopy measurements.

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: '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 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.
