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: 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: 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 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 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.

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 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: 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: 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: 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.
