text: "Populations evolve in spatially heterogeneous environments. While a certain
trait might bring a fitness advantage in some patch of the environment, a different
trait might be advantageous in another patch. Here, we study the Moran birth–death
process with two types of individuals in a population stretched across two patches
of size N, each patch favouring one of the two types. We show that the long-term
fate of such populations crucially depends on the migration rate μ\r\n between
the patches. To classify the possible fates, we use the distinction between polynomial
(short) and exponential (long) timescales. We show that when μ is high then one
of the two types fixates on the whole population after a number of steps that
is only polynomial in N. By contrast, when μ is low then each type holds majority
in the patch where it is favoured for a number of steps that is at least exponential
in N. Moreover, we precisely identify the threshold migration rate μ⋆ that separates
those two scenarios, thereby exactly delineating the situations that support long-term
coexistence of the two types. We also discuss the case of various cycle graphs
and we present computer simulations that perfectly match our analytical results."

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: Motivated by the recent discoveries of superconductivity in bilayer and trilayer
graphene, we theoretically investigate superconductivity and other interaction-driven
phases in multilayer graphene stacks. To this end, we study the density of states
of multilayer graphene with up to four layers at the single-particle band structure
level in the presence of a transverse electric field. Among the considered structures,
tetralayer graphene with rhombohedral (ABCA) stacking reaches the highest density
of states. We study the phases that can arise in ABCA graphene by tuning the carrier
density and transverse electric field. For a broad region of the tuning parameters,
the presence of strong Coulomb repulsion leads to a spontaneous spin and valley
symmetry breaking via Stoner transitions. Using a model that incorporates the
spontaneous spin and valley polarization, we explore the Kohn-Luttinger mechanism
for superconductivity driven by repulsive Coulomb interactions. We find that the
strongest superconducting instability is in the p-wave channel, and occurs in
proximity to the onset of Stoner transitions. Interestingly, we find a range of
densities and transverse electric fields where superconductivity develops out
of a strongly corrugated, singly connected Fermi surface in each valley, leading
to a topologically nontrivial chiral p+ip superconducting state with an even number
of copropagating chiral Majorana edge modes. Our work establishes ABCA-stacked
tetralayer graphene as a promising platform for observing strongly correlated
physics and topological superconductivity.

text: We investigate the capabilities of Physics-Informed Neural Networks (PINNs)
to reconstruct turbulent Rayleigh–Bénard flows using only temperature information.
We perform a quantitative analysis of the quality of the reconstructions at various
amounts of low-passed-filtered information and turbulent intensities. We compare
our results with those obtained via nudging, a classical equation-informed data
assimilation technique. At low Rayleigh numbers, PINNs are able to reconstruct
with high precision, comparable to the one achieved with nudging. At high Rayleigh
numbers, PINNs outperform nudging and are able to achieve satisfactory reconstruction
of the velocity fields only when data for temperature is provided with high spatial
and temporal density. When data becomes sparse, the PINNs performance worsens,
not only in a point-to-point error sense but also, and contrary to nudging, in
a statistical sense, as can be seen in the probability density functions and energy
spectra.

text: Interstitial fluid (IF) accumulation between embryonic cells is thought to
be important for embryo patterning and morphogenesis. Here, we identify a positive
mechanical feedback loop between cell migration and IF relocalization and find
that it promotes embryonic axis formation during zebrafish gastrulation. We show
that anterior axial mesendoderm (prechordal plate [ppl]) cells, moving in between
the yolk cell and deep cell tissue to extend the embryonic axis, compress the
overlying deep cell layer, thereby causing IF to flow from the deep cell layer
to the boundary between the yolk cell and the deep cell layer, directly ahead
of the advancing ppl. This IF relocalization, in turn, facilitates ppl cell protrusion
formation and migration by opening up the space into which the ppl moves and,
thereby, the ability of the ppl to trigger IF relocalization by pushing against
the overlying deep cell layer. Thus, embryonic axis formation relies on a hydraulic
feedback loop between cell migration and IF relocalization.

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: Universal nonequilibrium properties of isolated quantum systems are typically
probed by studying transport of conserved quantities, such as charge or spin,
while transport of energy has received considerably less attention. Here, we study
infinite-temperature energy transport in the kinetically constrained PXP model
describing Rydberg atom quantum simulators. Our state-of-the-art numerical simulations,
including exact diagonalization and time-evolving block decimation methods, reveal
the existence of two distinct transport regimes. At moderate times, the energy-energy
correlation function displays periodic oscillations due to families of eigenstates
forming different su(2) representations hidden within the spectrum. These families
of eigenstates generalize the quantum many-body scarred states found in previous
works and leave an imprint on the infinite-temperature energy transport. At later
times, we observe a long-lived superdiffusive transport regime that we attribute
to the proximity of a nearby integrable point. While generic strong deformations
of the PXP model indeed restore diffusive transport, adding a strong chemical
potential intriguingly gives rise to a well-converged superdiffusive exponent
z≈3/2. Our results suggest constrained models to be potential hosts of novel transport
regimes and call for developing an analytic understanding of their energy transport.

text: The development of cost-effective, high-activity and stable bifunctional catalysts
for the oxygen reduction and evolution reactions (ORR/OER) is essential for zinc–air
batteries (ZABs) to reach the market. Such catalysts must contain multiple adsorption/reaction
sites to cope with the high demands of reversible oxygen electrodes. Herein, we
propose a high entropy alloy (HEA) based on relatively abundant elements as a
bifunctional ORR/OER catalyst. More specifically, we detail the synthesis of a
CrMnFeCoNi HEA through a low-temperature solution-based approach. Such HEA displays
superior OER performance with an overpotential of 265 mV at a current density
of 10 mA/cm2, and a 37.9 mV/dec Tafel slope, well above the properties of a standard
commercial catalyst based on RuO2. This high performance is partially explained
by the presence of twinned defects, the incidence of large lattice distortions,
and the electronic synergy between the different components, being Cr key to decreasing
the energy barrier of the OER rate-determining step. CrMnFeCoNi also displays
superior ORR performance with a half-potential of 0.78 V and an onset potential
of 0.88 V, comparable with commercial Pt/C. The potential gap (Egap) between the
OER overpotential and the ORR half-potential of CrMnFeCoNi is just 0.734 V. Taking
advantage of these outstanding properties, ZABs are assembled using the CrMnFeCoNi
HEA as air cathode and a zinc foil as the anode. The assembled cells provide an
open-circuit voltage of 1.489 V, i.e. 90% of its theoretical limit (1.66 V), a
peak power density of 116.5 mW/cm2, and a specific capacity of 836 mAh/g that
stays stable for more than 10 days of continuous cycling, i.e. 720 cycles @ 8
mA/cm2 and 16.6 days of continuous cycling, i.e. 1200 cycles @ 5 mA/cm2.

text: Gears and cogwheels are elemental components of machines. They restrain degrees
of freedom and channel power into a specified motion. Building and powering small-scale
cogwheels are key steps toward feasible micro and nanomachinery. Assembly, energy
injection, and control are, however, a challenge at the microscale. In contrast
with passive gears, whose function is to transmit torques from one to another,
interlocking and untethered active gears have the potential to unveil dynamics
and functions untapped by externally driven mechanisms. Here, it is shown the
assembly and control of a family of self-spinning cogwheels with varying teeth
numbers and study the interlocking of multiple cogwheels. The teeth are formed
by colloidal microswimmers that power the structure. The cogwheels are autonomous
and active, showing persistent rotation. Leveraging the angular momentum of optical
vortices, we control the direction of rotation of the cogwheels. The pairs of
interlocking and active cogwheels that roll over each other in a random walk and
have curvature-dependent mobility are studied. This behavior is leveraged to self-position
parts and program microbots, demonstrating the ability to pick up, direct, and
release a load. The work constitutes a step toward autonomous machinery with external
control as well as (re)programmable microbots and matter.

text: The multicellular organization of diverse systems, including embryos, intestines,
and tumors relies on coordinated cell migration in curved environments. In these
settings, cells establish supracellular patterns of motion, including collective
rotation and invasion. While such collective modes have been studied extensively
in flat systems, the consequences of geometrical and topological constraints on
collective migration in curved systems are largely unknown. Here, we discover
a collective mode of cell migration in rotating spherical tissues manifesting
as a propagating single-wavelength velocity wave. This wave is accompanied by
an apparently incompressible supracellular flow pattern featuring topological
defects as dictated by the spherical topology. Using a minimal active particle
model, we reveal that this collective mode arises from the effect of curvature
on the active flocking behavior of a cell layer confined to a spherical surface.
Our results thus identify curvature-induced velocity waves as a mode of collective
cell migration, impacting the dynamical organization of 3D curved tissues.
