text: Finding the ground state of Ising spin glasses is notoriously difficult due
to disorder and frustration. Often, this challenge is framed as a combinatorial
optimization problem, for which a common strategy employs simulated annealing,
a Monte Carlo (MC)-based algorithm that updates spins one at a time. Yet, these
localized updates can cause the system to become trapped in local minima. Cluster
algorithms (CAs) were developed to address this limitation and have demonstrated
considerable success in studying ferromagnetic systems; however, they tend to
encounter percolation issues when applied to generic spin glasses. In this work,
we introduce a novel CA designed to tackle these challenges by leveraging precomputed
two-point correlations, aiming solve combinatorial optimization problems in the
form of Max-Cut more efficiently. In our approach, clusters are formed probabilistically
based on these correlations. Various classical and quantum algorithms can be employed
to generate correlations that embody information about the energy landscape of
the problem. By utilizing this information, the algorithm aims to identify groups
of spins whose simultaneous flipping induces large transitions in configuration
space with high acceptance probability - even at low energy levels - thereby escaping
local minima more effectively. Notably, clusters generated using correlations
from the Quantum Approximate Optimization Algorithm exhibit high acceptance rates
at low temperatures. These acceptance rates often increase with circuit depth,
accelerating the algorithm and enabling more efficient exploration of the solution
space.

text: The polarization of light is a critically under-utilized, rich source of information
in astronomy. For stars in particular, surface magnetism polarization that can
be detected and measured with spectro-polarimetry. Many questions about these
surface fields remain unanswered due to a lack of dedicated instruments capable
of probing weak and strong surface magnetic fields for the entire mass range of
stars, from M-dwarfs (and even substellar objects) to massive O-type stars at
different evolutionary stages and metallicities. These questions range from the
origin of these fields to their true incidence rate throughout the stellar population
and the dependence on metallicity. Magnetic fields, although currently often excluded
from stellar evolution models, play an important role in stellar evolution. Connecting
the surface fields to internal fields through asteroseismology will instigate
a new era of understanding stellar evolution and the transport of angular momentum
and chemical elements throughout stellar interiors, also impacting our understanding
of star-planet interactions and stellar remnants. Polarimetry is also an under-utilized
tool to observationally constrain the mode identification of nonradial oscillations,
which lies at the basis of accurate asteroseismic parameter estimation at percentage-level
for stellar radii, masses, ages, internal rotation, and magnetic field strengths.
Combining strong constraints on mode identification and surface magnetic properties
through the acquisition of time-resolved, high-resolution and high-signal-to-noise
(S/N) spectro-polarimetry and spectroscopy promises to bring leaps forward in
our understanding of stellar structure, particularly when combined with long-term
space photometric data from past, current, and future missions.

text: Accreting white dwarfs (WDs) in close binary systems, commonly known as cataclysmic
variables (CVs), with orbital periods below the canonical period minimum (≈80
minutes) are rare. Such short periods can only be reached if the donor star in
the CV is either significantly evolved before initiating mass transfer to the
WD or is metal-poor. We present optical photometry and spectroscopy of Gaia19bxc,
a high-amplitude variable identified as a polar CV with an exceptionally short
orbital period of 64.42 minutes—well below the canonical CV period minimum. High-speed
photometry confirms persistent double-peaked variability consistent with cyclotron
beaming, thus indicating the presence of a magnetic WD. Phase-resolved Keck/Low-Resolution
Imaging Spectrometer (LRIS) spectroscopy reveals strong hydrogen and helium emission
lines but no donor features, indicating the accretor is a magnetic WD and the
donor is hydrogen-rich, but cold and faint. The absence of a detectable donor
and the low inferred temperature (≲3500 K) disfavor an evolved donor scenario.
Instead, the short period and the system’s halo-like kinematics suggest Gaia19bxc
may be the first known metal-poor polar. Because metal-poor donors are more compact
than solar-metallicity donors of the same mass, they can reach shorter minimum
periods. Gaia19bxc is one of only a handful of known metal-poor CVs below the
canonical period minimum and has the shortest period of any such magnetic system
discovered to date.

text: Matter waves have been observed in double-slit experiments with microscopic
objects, such as atoms or molecules. The wave function describing the motion of
these objects must extend over a distance comparable to the slit separation, much
larger than the characteristic size of the objects. Preparing such states for
more massive objects, such as mechanical oscillators, remains an outstanding challenge.
Here we delocalize the quantum ground state of an optically levitated nanosphere
by modulating the stiffness of the confining potential. We show a more than threefold
increase of the initial coherence length, which corresponds to mechanical momentum
squeezing of more than 7 dB. Our work is a stepping stone toward the generation
of coherence lengths comparable to the object size, a crucial regime for macroscopic
quantum experiments.

text: 'The development of cost-effective and high-performance thermoelectric (TE)
materials faces significant challenges, particularly in improving the properties
of promising copper-based TE materials such as Cu3SbSe4, which are limited by
their poor electrical conductivity. This study presents a detailed comparative
analysis of three strategies to promote the electrical transport properties of
Cu3SbSe4 through Sn doping: conventional Sn atomic doping, surface treatment with
SnSe molecular complexes, and blending with SnSe nanocrystals to form nanocomposites,
all followed by annealing and hot pressing under identical conditions. Our results
reveal that a surface treatment using SnSe molecular complexes significantly enhances
TE performance over atomic doping and nanocomposite formation, achieving a power
factor of 1.1 mW·m−1·K−2 and a maximum dimensionless figure of merit zT value
of 0.80 at 640 K, representing an excellent performance among Cu3SbSe4-based materials
produced via solution-processing methods. This work highlights the effectiveness
of surface engineering in optimizing the transport properties of nanostructured
materials, demonstrating the versatility and cost-efficiency of solution-based
technologies in the development of advanced nanostructured materials for application
in the field of TE among others.'

text: Habitat fragmentation poses a significant risk to population survival, causing
both demographic stochasticity and genetic drift within local populations to increase,
thereby increasing genetic load. Higher load causes population numbers to decline,
which reduces the efficiency of selection and further increases load, resulting
in a positive feedback that may drive entire populations to extinction. Here,
we investigate this eco-evolutionary feedback in a metapopulation consisting of
local demes connected via migration, with individuals subject to deleterious mutation
at a large number of loci. We first analyze the determinants of load under soft
selection, where population sizes are fixed, and then build on this to understand
hard selection, where population sizes and load coevolve. We show that under soft
selection, very little gene flow (less than one migrant per generation) is enough
to prevent fixation of deleterious alleles. By contrast, much higher levels of
migration are required to mitigate load and prevent extinction when selection
is hard, with critical migration thresholds for metapopulation persistence increasing
sharply as the genome-wide deleterious mutation rate becomes comparable to the
baseline population growth rate. Moreover, critical migration thresholds are highest
if deleterious mutations have intermediate selection coefficients but lower if
alleles are predominantly recessive rather than additive (due to more efficient
purging of recessive load within local populations). Our analysis is based on
a combination of analytical approximations and simulations, allowing for a more
comprehensive understanding of the factors influencing load and extinction in
fragmented populations.

text: We present a unifying framework for proving the knowledge-soundness of KZG-like
polynomial commitment schemes, encompassing both univariate and multivariate variants.
By conceptualizing the proof technique of Lipmaa, Parisella, and Siim for the
univariate KZG scheme (EUROCRYPT 2024), we present tools and falsifiable hardness
assumptions that permit black-box extraction of the multivariate KZG scheme. Central
to our approach is the notion of a canonical Proof-of-Knowledge of a Polynomial
(PoKoP) of a polynomial commitment scheme, which we use to capture the extractability
notion required in constructions of practical zk-SNARKs. We further present an
explicit polynomial decomposition lemma for multivariate polynomials, enabling
a more direct analysis of interpolating extractors and bridging the gap between
univariate and multivariate commitments. Our results provide the first standard-model
proofs of extractability for the multivariate KZG scheme and many of its variants
under falsifiable assumptions.

text: Test-time training (TTT) methods explicitly update the weights of a model
to adapt to the specific test instance, and they have found success in a variety
of settings, including most recently language modeling and reasoning. To demystify
this success, we investigate a gradient-based TTT algorithm for in-context learning,
where we train a transformer model on the in-context demonstrations provided in
the test prompt. Specifically, we provide a comprehensive theoretical characterization
of linear transformers when the update rule is a single gradient step. Our theory
(i) delineates the role of alignment between pretraining distribution and target
task, (ii) demystifies how TTT can alleviate distribution shift, and (iii) quantifies
the sample complexity of TTT including how it can significantly reduce the eventual
sample size required for in-context learning. As our empirical contribution, we
study the benefits of TTT for TabPFN, a tabular foundation model. In line with
our theory, we demonstrate that TTT significantly reduces the required sample
size for tabular classification (3 to 5 times fewer) unlocking substantial inference
efficiency with a negligible training cost.

text: Proteins exist as a dynamic ensemble of multiple conformations, and these
motions are often crucial for their functions. However, current structure prediction
methods predominantly yield a single conformation, overlooking the conformational
heterogeneity revealed by diverse experimental modalities. Here, we present a
framework for building experiment-grounded protein structure generative models
that infer conformational ensembles consistent with measured experimental data.
The key idea is to treat stateof-the-art protein structure predictors (e.g., AlphaFold3)
as sequence-conditioned structural priors, and cast ensemble modeling as posterior
inference of protein structures given experimental measurements. Through extensive
real-data experiments, we demonstrate the generality of our method to incorporate
a variety of experimental measurements. In particular, our framework uncovers
previously unmodeled conformational heterogeneity from crystallographic densities,
and generates high-accuracy NMR ensembles orders of magnitude faster than the
status quo. Notably, we demonstrate that our ensembles outperform AlphaFold3 (Abramson
et al., 2024) and sometimes better fit experimental data than publicly deposited
structures to the Protein Data Bank (PDB, Burley et al. (2017)). We believe that
this approach will unlock building predictive models that fully embrace experimentally
observed conformational diversity.

text: Multi-index models provide a popular framework to investigate the learnability
of functions with low-dimensional structure and, also due to their connections
with neural networks, they have been object of recent intensive study. In this
paper, we focus on recovering the subspace spanned by the signals via spectral
estimators – a family of methods routinely used in practice, often as a warm-start
for iterative algorithms. Our main technical contribution is a precise asymptotic
characterization of the performance of spectral methods, when sample size and
input dimension grow proportionally and the dimension p of the space to recover
is fixed. Specifically, we locate the top-p eigenvalues of the spectral matrix
and establish the overlaps between the corresponding eigenvectors (which give
the spectral estimators) and a basis of the signal subspace. Our analysis unveils
a phase transition phenomenon in which, as the sample complexity grows, eigenvalues
escape from the bulk of the spectrum and, when that happens, eigenvectors recover
directions of the desired subspace. The precise characterization we put forward
enables the optimization of the data preprocessing, thus allowing to identify
the spectral estimator that requires the minimal sample size for weak recovery.

text: "We present a general framework for applying learning algorithms and heuristical
guidance to the verification of Markov decision processes (MDPs).\r\nThe primary
goal of our techniques is to improve performance by avoiding an exhaustive exploration
of the state space, instead focussing on particularly relevant areas of the system,
guided by heuristics. Our work builds on the previous results of Br{á}zdil et
al., significantly extending it as well as refining several details and fixing
errors.\r\nThe presented framework focuses on probabilistic reachability, which
is a core problem in verification, and is instantiated in two distinct scenarios.\r\nThe
first assumes that full knowledge of the MDP is available, in particular precise
transition probabilities. It performs a heuristic-driven partial exploration of
the model, yielding precise lower and upper bounds on the required probability.
The second tackles the case where we may only sample the MDP without knowing the
exact transition dynamics. Here, we obtain probabilistic guarantees, again in
terms of both the lower and upper bounds, which provides efficient stopping criteria
for the approximation. In particular, the latter is an extension of statistical
model-checking (SMC) for unbounded properties in MDPs. In contrast to other related
approaches, we do not restrict our attention to time-bounded (finite-horizon)
or discounted properties, nor assume any particular structural properties of the
MDP."

text: 'Several optical experiments have shown that in magnetic materials, the principal
axes of response tensors can rotate as an odd function of an applied magnetic
field. Here we offer a microscopic explanation of this effect, and we propose
a closely related dc transport phenomenon—an off-diagonal symmetric conductivity,
linear and odd in a magnetic field, which we refer to as linear magnetoconductivity
(LMC). Although LMC has the same functional dependence on a magnetic field as
the Hall effect, its origin is fundamentally different: LMC requires time-reversal
symmetry to be broken even before a magnetic field is applied, and is therefore
a sensitive probe of magnetism. We demonstrate LMC in three different ways: via
a tight-binding toy model, a density functional theory calculation on MnPSe3,
and a semiclassical treatment. The third approach identifies two distinct mechanisms
yielding LMC: momentum-dependent band magnetization and Berry curvature. Finally,
we propose an experimental geometry suitable for detecting LMC, and we demonstrate
its applicability using Landauer-Büttiker simulations. Our results emphasize the
importance of measuring the full conductivity tensor in magnetic materials, and
they introduce LMC as a new transport probe of symmetry.'

text: The interplay between symmetry and topology in magnetic materials makes it
possible to engineer exotic phases and technologically useful properties. A key
requirement for these pursuits is achieving control over local crystallographic
and magnetic structure, usually through sample morphology (such as synthesis of
bulk crystals versus thin films) and application of magnetic or electric fields.
Here we show that V1/3NbS2 can be crystallized in two ordered superlattices, distinguished
by the periodicity of out-of-plane magnetic intercalants. Whereas one of these
structures is metallic and displays the hallmarks of altermagnetism, the other
superlattice, which has not been isolated before in this family of intercalation
compounds, is a semimetallic noncollinear antiferromagnet that may enable access
to topologically nontrivial properties. This observation of an unconventional
superlattice structure establishes a powerful route for tailoring the tremendous
array of magnetic and electronic behaviors hosted in related materials and may
expand their use in low-power spintronic or topological quantum devices.

text: "Altermagnets, magnetic materials with zero magnetization and spin-split band
structure, have gained tremendous attention recently for their rich physics and
potential applications. Here, we report on a microscopic tight-binding model that
unveils a unique coupling between orbitals and spins in \U0001D451-wave altermagnets,
which gives rise to momentum-dependent and spin-selective optical absorption.
This coupling promotes the controlled optical excitation of up or down spins depending
on the polarization direction of linearly polarized light. Such an effect originates
from the coupling of orbitals to the sublattice degree of freedom through the
crystal field, which is then coupled to spins through the antiferromagnetic interaction.
Our crystal field analysis, which is general to any type of altermagnet, helps
understand the onset of altermagnetism from a microscopic point of view, and we
use our results to propose clear magneto-optical signatures of our predictions.
Our findings shine light on the interplay between orbitals and spins in altermagnets,
thus paving the way towards novel orbitronic and optospintronic devices."

text: Goldstone modes acquire a frequency gap in the presence of perturbations that
break the underlying continuous symmetry. Here, we study the response of a spin-based
Goldstone mode to strain and magnetic field in the broken helix, a multi-$\textbf{Q}$
phase of EuIn$_2$As$_2$. Optical polarimetry with spatial and temporal resolution
allows us to access information about both the structure and frequency of optically
excited spin-wave modes under different strain conditions. We observe nearly uniform
spin precession characteristic of a Goldstone mode only when magnetic field dominates
over strain. In this regime, the frequency depends linearly on the applied field.
A symmetry analysis for predicting the mode frequency near zero field demonstrates
that the observed scaling is of the lowest allowed order. This work thus demonstrates
the connections between magnetic symmetries and the frequency dependence of the
Goldstone mode in an external field, and illustrates the power of our technique
for studying the dynamics of complex magnets.

text: Multiferroic materials, in which electric polarization and magnetic order
coexist and couple, offer rich opportunities for both fundamental discovery and
technology. However, multiferroicity remains rare due to conflicting electronic
requirements for ferroelectricity and magnetism. One route to circumvent this
challenge is to exploit the noncollinear ordering of spin cycloids, whose symmetry
permits the emergence of polar order. In this work, we introduce another pathway
to multiferroic order in which strain generates polarization in materials that
host nonpolar spin spirals. To demonstrate this phenomenon, we chose the spin
spiral in the well-studied helimagnet Cr1/3NbS2. To detect the induced polarization,
we introduce the technique of magnetoelectric birefringence (MEB), an optical
probe that enables spatially-resolved and unambiguous detection of polar order.
By combining MEB imaging with strain engineering, we confirm the onset of a polar
vector at the magnetic transition, establishing strained Cr1/3NbS2 as a type-II
multiferroic.

text: Rendering novel, relit views of a human head, given a monocular portrait image
as input, is an inherently underconstrained problem. The traditional graphics
solution is to explicitly decompose the input image into geometry, material and
lighting via differentiable rendering; but this is constrained by the multiple
assumptions and approximations of the underlying models and parameterizations
of these scene components. We propose 3DPR, an image-based relighting model that
leverages generative priors learnt from multi-view One-Light-at-A-Time (OLAT)
images captured in a light stage. We introduce a new diverse and large-scale multi-view
4K OLAT dataset of 139 subjects to learn a high-quality prior over the distribution
of high-frequency face reflectance. We leverage the latent space of a pre-trained
generative head model that provides a rich prior over face geometry learnt from
in-the-wild image datasets. The input portrait is first embedded in the latent
manifold of such a model through an encoder-based inversion process. Then a novel
triplane-based reflectance network trained on our lightstage data is used to synthesize
high-fidelity OLAT images to enable image-based relighting. Our reflectance network
operates in the latent space of the generative head model, crucially enabling
a relatively small number of lightstage images to train the reflectance model.
Combining the generated OLATs according to a given HDRI environment maps yields
physically accurate environmental relighting results. Through quantitative and
qualitative evaluations, we demonstrate that 3DPR outperforms previous methods,
particularly in preserving identity and in capturing lighting effects such as
specularities, self-shadows, and subsurface scattering.

text: The property of a physical system is highly dependent on its dimensionality.
Topological physics in three or more dimensions exhibits rich phenomena without
lower-dimensional counterparts. In this paper, the authors propose a scheme to
implement such high-dimensional topological physics in a single photonic ring
resonator, where the model of interest can be arbitrarily high dimensional and
arbitrarily multi-band. The frequency modes in the resonator, coupled via electro-optic
modulation, are used to create a high-dimensional lattice, and the spatial modes
are used as the pseudo-spin degree of freedom within each lattice site. The band
structure of the model can be measured from the transmission spectrum of the ring
resonator. The authors numerically demonstrate as examples a three-dimensional,
two-band model and a five-dimensional, four-band model. This paper establishes
a versatile and programmable platform for high-dimensional topological physics,
paving the way for its experimental studies and future applications.

text: Fast-emitting scintillators are essential for advanced diagnostic techniques,
yet many suffer from low radiation attenuation. This trade-off is particularly
pronounced in polymer scintillators, which, despite their fast emission, exhibit
low density and low atomic numbers, limiting the radiation attenuation factor,
resulting in low detection efficiency. Here, we overcome this limitation by creating
a heterostructure scintillator of alternating nanometric layers, combining fast
light-emitting polymer scintillator layers and transparent stopping layers with
a high radiation attenuation factor. The nanolayer thicknesses are tuned to optimize
the penetration depth of recoil electrons in active emissive layers, maximizing
the conversion of X-rays to visible light. This design increases light output
by up to 1.5 times and enhances imaging resolution by a factor of 2 compared to
homogeneous polymer scintillators due to the ability to use thinner samples. These
results demonstrate the potential of heterostructure scintillators as next-generation
detector materials, overcoming the limitations of homogeneous scintillators.

text: In X-ray tubes, more than 99% of the kilowatts of power supplied to generate
X-rays via bremsstrahlung is lost as heat in the anode. Therefore, thermal management
is a critical barrier to the development of more powerful X-ray tubes with higher
brightness and spatial coherence, which are needed to translate imaging modalities
such as phase-contrast imaging to the clinic. In rotating anode X-ray tubes, the
most common design, thermal radiation is a bottleneck that prevents efficient
cooling of the anode─the hottest part of the device by far. We predict that nanophotonic
patterning of the anode of an X-ray tube enhances heat dissipation via thermal
radiation, enabling it to operate at higher powers without an increase in temperature.
The focal spot size, which is related to the spatial coherence of generated X-rays,
can also be reduced at a constant temperature. A major advantage of our “nanophotonic
thermal management” approach is that in principle, it allows complete control
over the spectrum and direction of thermal radiation, which can lead to optimal
thermal routing and improved performance.
