text: Cold atom experiments show that a mobile impurity particle immersed in a weakly
interacting Bose-Einstein condensate forms a well-defined quasiparticle (Bose
polaron) for weak to moderate impurity-boson interaction strengths, whereas a
significant line broadening is consistently observed for strong interactions.
Motivated by this, we introduce a phenomenological theory based on the assumption
that the most relevant states are characterized by the impurity correlated with
at most one boson, since they have the largest overlap with the uncorrelated states
to which the most common experimental probes couple. These experimentally relevant
states can, however, decay to lower energy states characterized by correlations
involving multiple bosons, and we model this using a minimal variational wave
function combined with a complex impurity-boson interaction strength. We first
motivate this approach by comparing to a more elaborate theory that includes correlations
with up to two bosons. Our phenomenological model is shown to recover the main
results of two recent experiments probing both the spectral and the nonequilibrium
properties of the Bose polaron. Our work offers an intuitive framework for analyzing
experimental data and highlights the importance of understanding the complicated
problem of the Bose polaron decay in a many-body setting.

text: We investigate quantum transport in a two-dimensional electron system coupled
to a chiral molecular potential, demonstrating how molecular chirality and orientation
affect charge and spin transport properties. We propose a minimal model for realizing
true chiral symmetry breaking on a magnetized surface, with a crucial role played
by the tilt angle of the molecular dipole with respect to the surface. For non-zero
tilting, we show that the Hall response exhibits clear signatures of chirality-induced
effects, in both charge- and spin-resolved observables. Concerning the former,
tilted enantiomers produce asymmetric Hall conductances and, even more remarkably,
the persistence of this feature in the absence of spin–orbit coupling (SOC) signals
how the enantiospecific charge response results from electron scattering off the
molecular potential. Concerning spin-resolved observables where SOC plays a relevant
role, we reveal that chiral symmetry breaking is crucial in enabling spin-flipping
processes.

text: The problem of mobile impurities in quantum baths is of fundamental importance
in many-body physics. There has recently been significant progress regarding our
understanding of this due to cold atom experiments, but so far it has mainly been
concerned with cases where the bath has no or only weak interactions, or the impurity
interacts weakly with the bath. Here, we address this gap by developing a new
theoretical framework for exploring a mobile impurity interacting strongly with
a highly correlated bath of bosons in the quantum critical regime of a Mott insulator
(MI) to superfluid (SF) quantum phase transition. Our framework is based on a
powerful quantum Gutzwiller (QGW) description of the bosonic bath combined with
diagrammatic field theory for the impurity-bath interactions. By resumming a selected
class of diagrams to infinite order, a rich picture emerges where the impurity
is dressed by the fundamental modes of the bath, which change character from gapped
particle-hole excitations in the MI to Higgs and gapless Goldstone modes in the
SF. This gives rise to the existence of several quasiparticle (polaron) branches
with properties reflecting the strongly correlated environment. In particular,
one polaron branch exhibits a sharp cusp in its energy, while a new ground-state
polaron emerges at the O(2) quantum phase transition point for integer filling,
which reflects the nonanalytic behavior at the transition and the appearance of
the Goldstone mode in the SF phase. Smooth versions of these features are inherited
in the polaron spectrum away from integer filling due to the influence of Mott
physics on the bosonic bath. We furthermore compare our diagrammatic results with
quantum Monte Carlo calculations, obtaining excellent agreement. This accuracy
is quite remarkable for such a highly non-trivial case of strong interactions
between the impurity and bosons in a maximally correlated quantum critical regime,
and it establishes the utility of our framework. Finally, our results show how
impurities can be used as quantum sensors and highlight fundamental differences
between experiments performed at a fixed particle number or a fixed chemical potential.

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: 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 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.
