text: The physical conditions giving rise to high escape fractions of ionizing radiation
(LyC fesc) in star-forming galaxies – most likely protagonists of cosmic reionization
– are not yet fully understood. Using the VLT/MUSE observations of ∼1400 Ly α
emitters at 2.9 < z < 6.7, we compare stacked rest-frame UV spectra
of candidates for LyC leakers and non-leakers selected based on their Ly α profiles.
We find that the stacks of potential LyC leakers, i.e. galaxies with narrow, symmetric
Ly α profiles with small peak separation, generally show (i) strong nebular O iii]λ1666,
[Si iii]λ1883, and [C iii]λ1907 +C iii]λ1909 emission, indicating a high-ionization
state of the interstellar medium (ISM); (ii) high equivalent widths of He iiλ1640
(∼1 − 3 Å), suggesting the presence of hard ionizing radiation fields; (iii) Si ii*λ1533
emission, revealing substantial amounts of neutral hydrogen off the line of sight;
(iv) high C ivλλ1548,1550 to [C iii]λ1907 +C iii]λ1909 ratios (C iv/C iii] ≳0.75)
, signalling the presence of low column density channels in the ISM. In contrast,
the stacks with broad, asymmetric Ly α profiles with large peak separation show
weak nebular emission lines, low He iiλ1640 equivalent widths (≲1 Å), and low
C iv/C iii] (≲0.25), implying low-ionization states and high-neutral hydrogen
column densities. Our results suggest that C iv/C iii] might be sensitive to the
physical conditions that govern LyC photon escape, providing a promising tool
for identification of ionizing sources among star-forming galaxies in the epoch
of reionization.

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: It may come as a surprise that a phenomenon as ubiquitous and prominent as
the transition from laminar to turbulent flow has resisted combined efforts by
physicists, engineers and mathematicians, and remained unresolved for almost one
and a half centuries. In recent years, various studies have proposed analogies
to directed percolation, a well-known universality class in statistical mechanics,
which describes a non-equilibrium phase transition from a fluctuating active phase
into an absorbing state. It is this unlikely relation between the multiscale,
high-dimensional dynamics that signify the transition process in virtually all
flows of practical relevance, and the arguably most basic non-equilibrium phase
transition, that so far has mainly been the subject of model studies, which I
review in this Perspective.

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: "Nominally identical materials exchange net electric charge during contact
through a mechanism that is still debated. ‘Mosaic models’, in which surfaces
are presumed to consist of a random patchwork of microscopic donor/acceptor sites,
offer an appealing explanation for this phenomenon. However, recent experiments
have shown that global differences persist even between same-material samples,
which the standard mosaic framework does not account for. Here, we expand the
mosaic framework by incorporating global differences in the densities of donor/acceptor
sites. We develop\r\nan analytical model, backed by numerical simulations, that
smoothly connects the global and deterministic charge transfer of different materials
to the local and stochastic mosaic picture normally associated with identical
materials. Going further, we extend our model to explain the effect of contact
asymmetries during sliding, providing a plausible explanation for reversal of
charging sign that has been observed experimentally."

text: Viscous flows through pipes and channels are steady and ordered until, with
increasing velocity, the laminar motion catastrophically breaks down and gives
way to turbulence. How this apparently discontinuous change from low- to high-dimensional
motion can be rationalized within the framework of the Navier-Stokes equations
is not well understood. Exploiting geometrical properties of transitional channel
flow we trace turbulence to far lower Reynolds numbers (Re) than previously possible
and identify the complete path that reversibly links fully turbulent motion to
an invariant solution. This precursor of turbulence destabilizes rapidly with
Re, and the accompanying explosive increase in attractor dimension effectively
marks the transition between deterministic and de facto stochastic dynamics.
acknowledgement: We thank Baofang Song as well as the developers of Channelflow for
sharing their numerical codes, and Mukund Vasudevan and Holger Kantz for fruitful
discussions. This work was supported by a grant from the Simons Foundation (662960,

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: The self-assembly of nanoparticles driven by small molecules or ions may produce
colloidal superlattices with features and properties reminiscent of those of metals
or semiconductors. However, to what extent the properties of such supramolecular
crystals actually resemble those of atomic materials often remains unclear. Here,
we present coarse-grained molecular simulations explicitly demonstrating how a
behavior evocative of that of semiconductors may emerge in a colloidal superlattice.
As a case study, we focus on gold nanoparticles bearing positively charged groups
that self-assemble into FCC crystals via mediation by citrate counterions. In
silico ohmic experiments show how the dynamically diverse behavior of the ions
in different superlattice domains allows the opening of conductive ionic gates
above certain levels of applied electric fields. The observed binary conductive/nonconductive
behavior is reminiscent of that of conventional semiconductors, while, at a supramolecular
level, crossing the “band gap” requires a sufficient electrostatic stimulus to
break the intermolecular interactions and make ions diffuse throughout the superlattice’s
cavities.

text: 'The ages of solar-like stars have been at the center of many studies such
as exoplanet characterization or Galactic-archeology. While ages are usually computed
from stellar evolution models, relations linking ages to other stellar properties,
such as rotation and magnetic activity, have been investigated. With the large
catalog of 55,232 rotation periods, Prot, and photometric magnetic activity index,
Sph from Kepler data, we have the opportunity to look for such magneto-gyro-chronology
relations. Stellar ages are obtained with two stellar evolution codes that include
treatment of angular momentum evolution, hence using Prot as input in addition
to classical atmospheric parameters. We explore two different ways of predicting
stellar ages on three subsamples with spectroscopic observations: solar analogs,
late-F and G dwarfs, and K dwarfs. We first perform a Bayesian analysis to derive
relations between Sph and ages between 1 and 5 Gyr, and other stellar properties.
For late-F and G dwarfs, and K dwarfs, the multivariate regression favors the
model with Prot and Sph with median differences of 0.1% and 0.2%, respectively.
We also apply Machine Learning techniques with a Random Forest algorithm to predict
ages up to 14 Gyr with the same set of input parameters. For late-F, G and K dwarfs
together, predicted ages are on average within 5.3% of the model ages and improve
to 3.1% when including Prot. These are very promising results for a quick age
estimation for solar-like stars with photometric observations, especially with
current and future space missions.'

text: Stars strongly impact their environment, and shape structures on all scales
throughout the universe, in a process known as "feedback." Due to the complexity
of both stellar evolution and the physics of larger astrophysical structures,
there remain many unanswered questions about how feedback operates and what we
can learn about stars by studying their imprint on the wider universe. In this
white paper, we summarize discussions from the Lorentz Center meeting "Bringing
Stellar Evolution and Feedback Together" in 2022 April and identify key areas
where further dialog can bring about radical changes in how we view the relationship
between stars and the universe they live in.

text: In previous work, we identified a population of 38 cool and luminous variable
stars in the Magellanic Clouds and examined 11 in detail in order to classify
them as either Thorne–Żytkow objects (TŻOs; red supergiants with a neutron star
cores) or super-asymptotic giant branch (sAGB) stars (the most massive stars that
will not undergo core collapse). This population includes HV 2112, a peculiar
star previously considered in other works to be either a TŻO or high-mass asymptotic
giant branch (AGB) star. Here we continue this investigation, using the kinematic
and radio environments and local star formation history of these stars to place
constraints on the age of the progenitor systems and the presence of past supernovae.
These stars are not associated with regions of recent star formation, and we find
no evidence of past supernovae at their locations. Finally, we also assess the
presence of heavy elements and lithium in their spectra compared to red supergiants.
We find strong absorption in Li and s-process elements compared to RSGs in most
of the sample, consistent with sAGB nucleosynthesis, while HV 2112 shows additional
strong lines associated with TŻO nucleosynthesis. Coupled with our previous mass
estimates, the results are consistent with the stars being massive (∼4–6.5 M⊙)
or sAGB (∼6.5–12 M⊙) stars in the thermally pulsing phase, providing crucial observations
of the transition between low- and high-mass stellar populations. HV 2112 is more
ambiguous; it could either be a maximally massive sAGB star, or a TŻO if the minimum
mass for stability extends down to ≲13 M⊙.

text: Characterizing and controlling entanglement in quantum materials is crucial
for the development of next-generation quantum technologies. However, defining
a quantifiable figure of merit for entanglement in macroscopic solids is theoretically
and experimentally challenging. At equilibrium the presence of entanglement can
be diagnosed by extracting entanglement witnesses from spectroscopic observables
and a nonequilibrium extension of this method could lead to the discovery of novel
dynamical phenomena. Here, we propose a systematic approach to quantify the time-dependent
quantum Fisher information and entanglement depth of transient states of quantum
materials with time-resolved resonant inelastic x-ray scattering. Using a quarter-filled
extended Hubbard model as an example, we benchmark the efficiency of this approach
and predict a light-enhanced many-body entanglement due to the proximity to a
phase boundary. Our work sets the stage for experimentally witnessing and controlling
entanglement in light-driven quantum materials via ultrafast spectroscopic measurements.

text: Many-body entanglement in condensed matter systems can be diagnosed from equilibrium
response functions through the use of entanglement witnesses and operator-specific
quantum bounds. Here, we investigate the applicability of this approach for detecting
entangled states in quantum systems driven out of equilibrium. We use a multipartite
entanglement witness, the quantum Fisher information, to study the dynamics of
a paradigmatic fermion chain undergoing a time-dependent change of the Coulomb
interaction. Our results show that the quantum Fisher information is able to witness
distinct signatures of multipartite entanglement both near and far from equilibrium
that are robust against decoherence. We discuss implications of these findings
for probing entanglement in light-driven quantum materials with time-resolved
optical and x-ray scattering methods.

text: Arrays of Josephson junctions are governed by a competition between superconductivity
and repulsive Coulomb interactions, and are expected to exhibit diverging low-temperature
resistance when interactions exceed a critical level. Here we report a study of
the transport and microwave response of Josephson arrays with interactions exceeding
this level. Contrary to expectations, we observe that the array resistance drops
dramatically as the temperature is decreased—reminiscent of superconducting behaviour—and
then saturates at low temperature. Applying a magnetic field, we eventually observe
a transition to a highly resistive regime. These observations can be understood
within a theoretical picture that accounts for the effect of thermal fluctuations
on the insulating phase. On the basis of the agreement between experiment and
theory, we suggest that apparent superconductivity in our Josephson arrays arises
from melting the zero-temperature insulator.

text: Observations of individual massive stars, super-luminous supernovae, gamma-ray
bursts, and gravitational wave events involving spectacular black hole mergers
indicate that the low-metallicity Universe is fundamentally different from our
own Galaxy. Many transient phenomena will remain enigmatic until we achieve a
firm understanding of the physics and evolution of massive stars at low metallicity
(Z). The Hubble Space Telescope has devoted 500 orbits to observing ∼250 massive
stars at low Z in the ultraviolet (UV) with the COS and STIS spectrographs under
the ULLYSES programme. The complementary X-Shooting ULLYSES (XShootU) project
provides an enhanced legacy value with high-quality optical and near-infrared
spectra obtained with the wide-wavelength coverage X-shooter spectrograph at ESO’s
Very Large Telescope. We present an overview of the XShootU project, showing that
combining ULLYSES UV and XShootU optical spectra is critical for the uniform determination
of stellar parameters such as effective temperature, surface gravity, luminosity,
and abundances, as well as wind properties such as mass-loss rates as a function
of Z. As uncertainties in stellar and wind parameters percolate into many adjacent
areas of astrophysics, the data and modelling of the XShootU project is expected
to be a game changer for our physical understanding of massive stars at low Z.
To be able to confidently interpret James Webb Space Telescope spectra of the
first stellar generations, the individual spectra of low-Z stars need to be understood,
which is exactly where XShootU can deliver.

text: 'Thorne–Żytkow objects (TŻO) are potential end products of the merger of a
neutron star with a non-degenerate star. In this work, we have computed the first
grid of evolutionary models of TŻOs with the MESA stellar evolution code. With
these models, we predict several observational properties of TŻOs, including their
surface temperatures and luminosities, pulsation periods, and nucleosynthetic
products. We expand the range of possible TŻO solutions to cover 3.45≲log(Teff/K)≲3.65
and 4.85≲log(L/L⊙)≲5.5. Due to the much higher densities our TŻOs reach compared
to previous models, if TŻOs form we expect them to be stable over a larger mass
range than previously predicted, without exhibiting a gap in their mass distribution.
Using the GYRE stellar pulsation code we show that TŻOs should have fundamental
pulsation periods of 1000–2000 d, and period ratios of ≈0.2–0.3. Models computed
with a large 399 isotope fully coupled nuclear network show a nucleosynthetic
signal that is different to previously predicted. We propose a new nucleosynthetic
signal to determine a star’s status as a TŻO: the isotopologues 44TiO2 and 44TiO,
which will have a shift in their spectral features as compared to stable titanium-containing
molecules. We find that in the local Universe (∼SMC metallicities and above) TŻOs
show little heavy metal enrichment, potentially explaining the difficulty in finding
TŻOs to-date.'

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: Quantum kinetically constrained models have recently attracted significant
attention due to their anomalous dynamics and thermalization. In this work, we
introduce a hitherto unexplored family of kinetically constrained models featuring
conserved particle number and strong inversion-symmetry breaking due to facilitated
hopping. We demonstrate that these models provide a generic example of so-called
quantum Hilbert space fragmentation, that is manifested in disconnected sectors
in the Hilbert space that are not apparent in the computational basis. Quantum
Hilbert space fragmentation leads to an exponential in system size number of eigenstates
with exactly zero entanglement entropy across several bipartite cuts. These eigenstates
can be probed dynamically using quenches from simple initial product states. In
addition, we study the particle spreading under unitary dynamics launched from
the domain wall state, and find faster than diffusive dynamics at high particle
densities, that crosses over into logarithmically slow relaxation at smaller densities.
Using a classically simulable cellular automaton, we reproduce the logarithmic
dynamics observed in the quantum case. Our work suggests that particle conserving
constrained models with inversion symmetry breaking realize so far unexplored
dynamical behavior and invite their further theoretical and experimental studies.

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
