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: 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: '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 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: 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: We present a numerical analysis of spin-1/2 fermions in a one-dimensional
harmonic potential in the presence of a magnetic point-like impurity at the center
of the trap. The model represents a few-body analogue of a magnetic impurity in
the vicinity of an s-wave superconductor. Already for a few particles we find
a ground-state level crossing between sectors with different fermion parities.
We interpret this crossing as a few-body precursor of a quantum phase transition,
which occurs when the impurity "breaks" a Cooper pair. This picture is further
corroborated by analyzing density-density correlations in momentum space. Finally,
we discuss how the system may be realized with existing cold-atoms platforms.

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: The model of a ring threaded by the Aharonov-Bohm flux underlies our understanding
of a coupling between gauge potentials and matter. The typical formulation of
the model is based upon a single particle picture, and should be extended when
interactions with other particles become relevant. Here, we illustrate such an
extension for a particle in an Aharonov-Bohm ring subject to interactions with
a weakly interacting Bose gas. We show that the ground state of the system can
be described using the Bose-polaron concept—a particle dressed by interactions
with a bosonic environment. We connect the energy spectrum to the effective mass
of the polaron, and demonstrate how to change currents in the system by tuning
boson-particle interactions. Our results suggest the Aharonov-Bohm ring as a platform
for studying coherence and few- to many-body crossover of quasi-particles that
arise from an impurity immersed in a medium.

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: Cold atomic gases have become a paradigmatic system for exploring fundamental
physics, which at the same time allows for applications in quantum technologies.
The accelerating developments in the field have led to a highly advanced set of
engineering techniques that, for example, can tune interactions, shape the external
geometry, select among a large set of atomic species with different properties,
or control the number of atoms. In particular, it is possible to operate in lower
dimensions and drive atomic systems into the strongly correlated regime. In this
review, we discuss recent advances in few-body cold atom systems confined in low
dimensions from a theoretical viewpoint. We mainly focus on bosonic systems in
one dimension and provide an introduction to the static properties before we review
the state-of-the-art research into quantum dynamical processes stimulated by the
presence of correlations. Besides discussing the fundamental physical phenomena
arising in these systems, we also provide an overview of the calculational and
numerical tools and methods that are commonly used, thus delivering a balanced
and comprehensive overview of the field. We conclude by giving an outlook on possible
future directions that are interesting to explore in these correlated systems.

text: We study the out-of-equilibrium quantum dynamics of dipolar polarons, i.e.,
impurities immersed in a dipolar Bose-Einstein condensate, after a quench of the
impurity-boson interaction. We show that the dipolar nature of the condensate
and of the impurity results in anisotropic relaxation dynamics, in particular,
anisotropic dressing of the polaron. More relevantly for cold-atom setups, quench
dynamics is strongly affected by the interplay between dipolar anisotropy and
trap geometry. Our findings pave the way for simulating impurities in anisotropic
media utilizing experiments with dipolar mixtures.

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: '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: We employ the Gross-Pitaevskii equation to study acoustic emission generated
in a uniform Bose gas by a static impurity. The impurity excites a sound-wave
packet, which propagates through the gas. We calculate the shape of this wave
packet in the limit of long wave lengths, and argue that it is possible to extract
properties of the impurity by observing this shape. We illustrate here this possibility
for a Bose gas with a trapped impurity atom -- an example of a relevant experimental
setup. Presented results are general for all one-dimensional systems described
by the nonlinear Schrödinger equation and can also be used in nonatomic systems,
e.g., to analyze light propagation in nonlinear optical media. Finally, we calculate
the shape of the sound-wave packet for a three-dimensional Bose gas assuming a
spherically symmetric perturbation.

text: Theoretical and experimental studies of the interaction between spins and
temperature are vital for the development of spin caloritronics, as they dictate
the design of future devices. In this work, we propose a two-terminal cold-atom
simulator to study that interaction. The proposed quantum simulator consists of
strongly interacting atoms that occupy two temperature reservoirs connected by
a one-dimensional link. First, we argue that the dynamics in the link can be described
using an inhomogeneous Heisenberg spin chain whose couplings are defined by the
local temperature. Second, we show the existence of a spin current in a system
with a temperature difference by studying the dynamics that follows the spin-flip
of an atom in the link. A temperature gradient accelerates the impurity in one
direction more than in the other, leading to an overall spin current similar to
the spin Seebeck effect.

text: The relative motion of three impenetrable particles on a ring, in our case
two identical fermions and one impurity, is isomorphic to a triangular quantum
billiard. Depending on the ratio κ of the impurity and fermion masses, the billiards
can be integrable or non-integrable (also referred to in the main text as chaotic).
To set the stage, we first investigate the energy level distributions of the billiards
as a function of 1/κ ∈ [0, 1] and find no evidence of integrable cases beyond
the limiting values 1/κ = 1 and 1/κ = 0. Then, we use machine learning tools to
analyze properties of probability distributions of individual quantum states.
We find that convolutional neural networks can correctly classify integrable and
non-integrable states. The decisive features of the wave functions are the normalization
and a large number of zero elements, corresponding to the existence of a nodal
line. The network achieves typical accuracies of 97%, suggesting that machine
learning tools can be used to analyze and classify the morphology of probability
densities obtained in theory or experiment.
