text: 'Theoretical foundations of chaos have been predominantly laid out for finite-dimensional
dynamical systems, such as the three-body problem in classical mechanics and the
Lorenz model in dissipative systems. In contrast, many real-world chaotic phenomena,
e.g., weather, arise in systems with many (formally infinite) degrees of freedom,
which limits direct quantitative analysis of such systems using chaos theory.
In the present work, we demonstrate that the hydrodynamic pilot-wave systems offer
a bridge between low- and high-dimensional chaotic phenomena by allowing for a
systematic study of how the former connects to the latter. Specifically, we present
experimental results, which show the formation of low-dimensional chaotic attractors
upon destabilization of regular dynamics and a final transition to high-dimensional
chaos via the merging of distinct chaotic regions through a crisis bifurcation.
Moreover, we show that the post-crisis dynamics of the system can be rationalized
as consecutive scatterings from the nonattracting chaotic sets with lifetimes
following exponential distributions. '

text: Cell migration in confining physiological environments relies on the concerted
dynamics of several cellular components, including protrusions, adhesions with
the environment, and the cell nucleus. However, it remains poorly understood how
the dynamic interplay of these components and the cell polarity determine the
emergent migration behavior at the cellular scale. Here, we combine data-driven
inference with a mechanistic bottom-up approach to develop a model for protrusion
and polarity dynamics in confined cell migration, revealing how the cellular dynamics
adapt to confining geometries. Specifically, we use experimental data of joint
protrusion-nucleus migration trajectories of cells on confining micropatterns
to systematically determine a mechanistic model linking the stochastic dynamics
of cell polarity, protrusions, and nucleus. This model indicates that the cellular
dynamics adapt to confining constrictions through a switch in the polarity dynamics
from a negative to a positive self-reinforcing feedback loop. Our model further
reveals how this feedback loop leads to stereotypical cycles of protrusion-nucleus
dynamics that drive the migration of the cell through constrictions. These cycles
are disrupted upon perturbation of cytoskeletal components, indicating that the
positive feedback is controlled by cellular migration mechanisms. Our data-driven
theoretical approach therefore identifies polarity feedback adaptation as a key
mechanism in confined cell migration.

text: 'We consider the problem of estimating a signal from measurements obtained
via a generalized linear model. We focus on estimators based on approximate message
passing (AMP), a family of iterative algorithms with many appealing features:
the performance of AMP in the high-dimensional limit can be succinctly characterized
under suitable model assumptions; AMP can also be tailored to the empirical distribution
of the signal entries, and for a wide class of estimation problems, AMP is conjectured
to be optimal among all polynomial-time algorithms. However, a major issue of
AMP is that in many models (such as phase retrieval), it requires an initialization
correlated with the ground-truth signal and independent from the measurement matrix.
Assuming that such an initialization is available is typically not realistic.
In this paper, we solve this problem by proposing an AMP algorithm initialized
with a spectral estimator. With such an initialization, the standard AMP analysis
fails since the spectral estimator depends in a complicated way on the design
matrix. Our main contribution is a rigorous characterization of the performance
of AMP with spectral initialization in the high-dimensional limit. The key technical
idea is to define and analyze a two-phase artificial AMP algorithm that first
produces the spectral estimator, and then closely approximates the iterates of
the true AMP. We also provide numerical results that demonstrate the validity
of the proposed approach.'

text: In this work, a feed-forward artificial neural network (FF-ANN) design capable
of locating eigensolutions to Schrödinger's equation via self-supervised learning
is outlined. Based on the input potential determining the nature of the quantum
problem, the presented FF-ANN strategy identifies valid solutions solely by minimizing
Schrödinger's equation encoded in a suitably designed global loss function. In
addition to benchmark calculations of prototype systems with known analytical
solutions, the outlined methodology was also applied to experimentally accessible
quantum systems, such as the vibrational states of molecular hydrogen H2 and its
isotopologues HD and D2 as well as the torsional tunnel splitting in the phenol
molecule. It is shown that in conjunction with the use of SIREN activation functions
a high accuracy in the energy eigenvalues and wavefunctions is achieved without
the requirement to adjust the implementation to the vastly different range of
input potentials, thereby even considering problems under periodic boundary conditions.

text: We report the observation of an anomalous nonlinear optical response of the
prototypical three-dimensional topological insulator bismuth selenide through
the process of high-order harmonic generation. We find that the generation efficiency
increases as the laser polarization is changed from linear to elliptical, and
it becomes maximum for circular polarization. With the aid of a microscopic theory
and a detailed analysis of the measured spectra, we reveal that such anomalous
enhancement encodes the characteristic topology of the band structure that originates
from the interplay of strong spin–orbit coupling and time-reversal symmetry protection.
The implications are in ultrafast probing of topological phase transitions, light-field
driven dissipationless electronics, and quantum computation.

text: The analogy between an equilibrium partition function and the return probability
in many-body unitary dynamics has led to the concept of dynamical quantum phase
transition (DQPT). DQPTs are defined by nonanalyticities in the return amplitude
and are present in many models. In some cases, DQPTs can be related to equilibrium
concepts, such as order parameters, yet their universal description is an open
question. In this Letter, we provide first steps toward a classification of DQPTs
by using a matrix product state description of unitary dynamics in the thermodynamic
limit. This allows us to distinguish the two limiting cases of “precession” and
“entanglement” DQPTs, which are illustrated using an analytical description in
the quantum Ising model. While precession DQPTs are characterized by a large entanglement
gap and are semiclassical in their nature, entanglement DQPTs occur near avoided
crossings in the entanglement spectrum and can be distinguished by a complex pattern
of nonlocal correlations. We demonstrate the existence of precession and entanglement
DQPTs beyond Ising models, discuss observables that can distinguish them, and
relate their interplay to complex DQPT phenomenology.

text: "We show that the energy gap for the BCS gap equation is\r\nΞ=μ(8e−2+o(1))exp(π2μ−−√a)\r\nin
the low density limit μ→0. Together with the similar result for the critical temperature
by Hainzl and Seiringer (Lett Math Phys 84: 99–107, 2008), this shows that, in
the low density limit, the ratio of the energy gap and critical temperature is
a universal constant independent of the interaction potential V. The results hold
for a class of potentials with negative scattering length a and no bound states."

text: While several tools have been developed to study the ground state of many-body
quantum spin systems, the limitations of existing techniques call for the exploration
of new approaches. In this manuscript we develop an alternative analytical and
numerical framework for many-body quantum spin ground states, based on the disentanglement
formalism. In this approach, observables are exactly expressed as Gaussian-weighted
functional integrals over scalar fields. We identify the leading contribution
to these integrals, given by the saddle point of a suitable effective action.
Analytically, we develop a field-theoretical expansion of the functional integrals,
performed by means of appropriate Feynman rules. The expansion can be truncated
to a desired order to obtain analytical approximations to observables. Numerically,
we show that the disentanglement approach can be used to compute ground state
expectation values from classical stochastic processes. While the associated fluctuations
grow exponentially with imaginary time and the system size, this growth can be
mitigated by means of an importance sampling scheme based on knowledge of the
saddle point configuration. We illustrate the advantages and limitations of our
methods by considering the quantum Ising model in 1, 2 and 3 spatial dimensions.
Our analytical and numerical approaches are applicable to a broad class of systems,
bridging concepts from quantum lattice models, continuum field theory, and classical
stochastic processes.

text: Cu2–xS has become one of the most promising thermoelectric materials for application
in the middle-high temperature range. Its advantages include the abundance, low
cost, and safety of its elements and a high performance at relatively elevated
temperatures. However, stability issues limit its operation current and temperature,
thus calling for the optimization of the material performance in the middle temperature
range. Here, we present a synthetic protocol for large scale production of covellite
CuS nanoparticles at ambient temperature and atmosphere, and using water as a
solvent. The crystal phase and stoichiometry of the particles are afterward tuned
through an annealing process at a moderate temperature under inert or reducing
atmosphere. While annealing under argon results in Cu1.8S nanopowder with a rhombohedral
crystal phase, annealing in an atmosphere containing hydrogen leads to tetragonal
Cu1.96S. High temperature X-ray diffraction analysis shows the material annealed
in argon to transform to the cubic phase at ca. 400 K, while the material annealed
in the presence of hydrogen undergoes two phase transitions, first to hexagonal
and then to the cubic structure. The annealing atmosphere, temperature, and time
allow adjustment of the density of copper vacancies and thus tuning of the charge
carrier concentration and material transport properties. In this direction, the
material annealed under Ar is characterized by higher electrical conductivities
but lower Seebeck coefficients than the material annealed in the presence of hydrogen.
By optimizing the charge carrier concentration through the annealing time, Cu2–xS
with record figures of merit in the middle temperature range, up to 1.41 at 710
K, is obtained. We finally demonstrate that this strategy, based on a low-cost
and scalable solution synthesis process, is also suitable for the production of
high performance Cu2–xS layers using high throughput and cost-effective printing
technologies.

text: Several Ising-type magnetic van der Waals (vdW) materials exhibit stable magnetic
ground states. Despite these clear experimental demonstrations, a complete theoretical
and microscopic understanding of their magnetic anisotropy is still lacking. In
particular, the validity limit of identifying their one-dimensional (1-D) Ising
nature has remained uninvestigated in a quantitative way. Here we performed the
complete mapping of magnetic anisotropy for a prototypical Ising vdW magnet FePS3
for the first time. Combining torque magnetometry measurements with their magnetostatic
model analysis and the relativistic density functional total energy calculations,
we successfully constructed the three-dimensional (3-D) mappings of the magnetic
anisotropy in terms of magnetic torque and energy. The results not only quantitatively
confirm that the easy axis is perpendicular to the ab plane, but also reveal the
anisotropies within the ab, ac, and bc planes. Our approach can be applied to
the detailed quantitative study of magnetism in vdW materials.

text: We first review the problem of a rigorous justification of Kubo’s formula
for transport coefficients in gapped extended Hamiltonian quantum systems at zero
temperature. In particular, the theoretical understanding of the quantum Hall
effect rests on the validity of Kubo’s formula for such systems, a connection
that we review briefly as well. We then highlight an approach to linear response
theory based on non-equilibrium almost-stationary states (NEASS) and on a corresponding
adiabatic theorem for such systems that was recently proposed and worked out by
one of us in [51] for interacting fermionic systems on finite lattices. In the
second part of our paper, we show how to lift the results of [51] to infinite
systems by taking a thermodynamic limit.

text: Inositol hexakisphosphate (IP6) is an assembly cofactor for HIV-1. We report
here that IP6 is also used for assembly of Rous sarcoma virus (RSV), a retrovirus
from a different genus. IP6 is ~100-fold more potent at promoting RSV mature capsid
protein (CA) assembly than observed for HIV-1 and removal of IP6 in cells reduces
infectivity by 100-fold. Here, visualized by cryo-electron tomography and subtomogram
averaging, mature capsid-like particles show an IP6-like density in the CA hexamer,
coordinated by rings of six lysines and six arginines. Phosphate and IP6 have
opposing effects on CA in vitro assembly, inducing formation of T = 1 icosahedrons
and tubes, respectively, implying that phosphate promotes pentamer and IP6 hexamer
formation. Subtomogram averaging and classification optimized for analysis of
pleomorphic retrovirus particles reveal that the heterogeneity of mature RSV CA
polyhedrons results from an unexpected, intrinsic CA hexamer flexibility. In contrast,
the CA pentamer forms rigid units organizing the local architecture. These different
features of hexamers and pentamers determine the structural mechanism to form
CA polyhedrons of variable shape in mature RSV particles.

(OER) shifts more significantly than the hydrogen evolution reaction (HER) does.
The OER shift has been explained by the accumulation of hydrophobic anions blocking
water access to the electrode surface, hence by double layer theory. Here we demonstrate
that the processes during oxidation are much more complex, involving OER, carbon
and salt decomposition by OER intermediates, and salt precipitation upon local
oversaturation. The positive shift in the onset potential of oxidation currents
was elucidated by combining several advanced analysis techniques: rotating ring-disk
electrode voltammetry, online electrochemical mass spectrometry, and X-ray photoelectron
spectroscopy, using both dilute and superconcentrated electrolytes. The results
demonstrate the importance of reactive OER intermediates and surface films for
electrolyte and electrode stability and motivate further studies of the nature
of the electrode.'

text: The hexameric AAA-ATPase Drg1 is a key factor in eukaryotic ribosome biogenesis
and initiates cytoplasmic maturation of the large ribosomal subunit by releasing
the shuttling maturation factor Rlp24. Drg1 monomers contain two AAA-domains (D1
and D2) that act in a concerted manner. Rlp24 release is inhibited by the drug
diazaborine which blocks ATP hydrolysis in D2. The mode of inhibition was unknown.
Here we show the first cryo-EM structure of Drg1 revealing the inhibitory mechanism.
Diazaborine forms a covalent bond to the 2′-OH of the nucleotide in D2, explaining
its specificity for this site. As a consequence, the D2 domain is locked in a
rigid, inactive state, stalling the whole Drg1 hexamer. Resistance mechanisms
identified include abolished drug binding and altered positioning of the nucleotide.
Our results suggest nucleotide-modifying compounds as potential novel inhibitors
for AAA-ATPases.

text: Ferromagnetism is most common in transition metal compounds but may also arise
in low-density two-dimensional electron systems, with signatures observed in silicon,
III-V semiconductor systems, and graphene moiré heterostructures. Here we show
that gate-tuned van Hove singularities in rhombohedral trilayer graphene drive
the spontaneous ferromagnetic polarization of the electron system into one or
more spin- and valley flavors. Using capacitance measurements on graphite-gated
van der Waals heterostructures, we find a cascade of density- and electronic displacement
field tuned phase transitions marked by negative electronic compressibility. The
transitions define the boundaries between phases where quantum oscillations have
either four-fold, two-fold, or one-fold degeneracy, associated with a spin and
valley degenerate normal metal, spin-polarized `half-metal', and spin and valley
polarized `quarter metal', respectively. For electron doping, the salient features
are well captured by a phenomenological Stoner model with a valley-anisotropic
Hund's coupling, likely arising from interactions at the lattice scale. For hole
filling, we observe a richer phase diagram featuring a delicate interplay of broken
symmetries and transitions in the Fermi surface topology. Finally, by rotational
alignment of a hexagonal boron nitride substrate to induce a moiré superlattice,
we find that the superlattice perturbs the preexisting isospin order only weakly,
leaving the basic phase diagram intact while catalyzing the formation of topologically
nontrivial gapped states whenever itinerant half- or quarter metal states occur
at half- or quarter superlattice band filling. Our results show that rhombohedral
trilayer graphene is an ideal platform for well-controlled tests of many-body
theory and reveal magnetism in moiré materials to be fundamentally itinerant in
nature.

text: We investigate the effect of coupling between translational and internal degrees
of freedom of composite quantum particles on their localization in a random potential.
We show that entanglement between the two degrees of freedom weakens localization
due to the upper bound imposed on the inverse participation ratio by purity of
a quantum state. We perform numerical calculations for a two-particle system bound
by a harmonic force in a 1D disordered lattice and a rigid rotor in a 2D disordered
lattice. We illustrate that the coupling has a dramatic effect on localization
properties, even with a small number of internal states participating in quantum
dynamics.

text: The C-terminal domain (CTD) of the largest subunit of RNA polymerase II (Pol
II) is a regulatory hub for transcription and RNA processing. Here, we identify
PHD-finger protein 3 (PHF3) as a regulator of transcription and mRNA stability
that docks onto Pol II CTD through its SPOC domain. We characterize SPOC as a
CTD reader domain that preferentially binds two phosphorylated Serine-2 marks
in adjacent CTD repeats. PHF3 drives liquid-liquid phase separation of phosphorylated
Pol II, colocalizes with Pol II clusters and tracks with Pol II across the length
of genes. PHF3 knock-out or SPOC deletion in human cells results in increased
Pol II stalling, reduced elongation rate and an increase in mRNA stability, with
marked derepression of neuronal genes. Key neuronal genes are aberrantly expressed
in Phf3 knock-out mouse embryonic stem cells, resulting in impaired neuronal differentiation.
Our data suggest that PHF3 acts as a prominent effector of neuronal gene regulation
by bridging transcription with mRNA decay.

text: We study the effects of osmotic shocks on lipid vesicles via coarse-grained
molecular dynamics simulations by explicitly considering the solute in the system.
We find that depending on their nature (hypo- or hypertonic) such shocks can lead
to bursting events or engulfing of external material into inner compartments,
among other morphology transformations. We characterize the dynamics of these
processes and observe a separation of time scales between the osmotic shock absorption
and the shape relaxation. Our work consequently provides an insight into the dynamics
of compartmentalization in vesicular systems as a result of osmotic shocks, which
can be of interest in the context of early proto-cell development and proto-cell
compartmentalisation.

text: We show that in a two-dimensional electron gas with an annular Fermi surface,
long-range Coulomb interactions can lead to unconventional superconductivity by
the Kohn-Luttinger mechanism. Superconductivity is strongly enhanced when the
inner and outer Fermi surfaces are close to each other. The most prevalent state
has chiral p-wave symmetry, but d-wave and extended s-wave pairing are also possible.
We discuss these results in the context of rhombohedral trilayer graphene, where
superconductivity was recently discovered in regimes where the normal state has
an annular Fermi surface. Using realistic parameters, our mechanism can account
for the order of magnitude of Tc, as well as its trends as a function of electron
density and perpendicular displacement field. Moreover, it naturally explains
some of the outstanding puzzles in this material, that include the weak temperature
dependence of the resistivity above Tc, and the proximity of spin singlet superconductivity
to the ferromagnetic phase.
