This study utilizes the Bogoliubov approach in a ring-shaped Bose-Einstein condensate to demonstrate that quantum depletion increases with Hawking temperature due to horizon dynamics, revealing a critical threshold where backreaction effects challenge the approximation's validity while identifying a viable parameter regime for experimental investigation.
This study introduces a factorized-implicit Fourier Neural Operator (F-IFNO) framework that enhances long-term stability and accuracy in predicting three-dimensional turbulence by integrating uncertainty quantification and error propagation analysis to overcome the limitations of traditional models and existing neural operators.
This paper utilizes two-dimensional molecular dynamics simulations to introduce a wavenumber-dependent viscosity that unifies renormalized and bare viscosity by demonstrating how equilibrium stress correlations diverge at small wavenumbers while determining bare viscosity at large wavenumbers, thereby bridging mesoscopic fluctuations and macroscopic transport through microscopic dynamics.
This paper demonstrates that the saddle-point configuration for thermal phase slips in an infinite superconducting film near the critical current is exactly solvable via the Boussinesq equation, revealing specific scaling laws for the instanton size and activation energy that explain the behavior of superconducting strips used in photon detection.
This paper introduces Structured Kolmogorov-Arnold Neural ODEs (SKANODEs), a framework that combines structured state-space modeling with Kolmogorov-Arnold Networks to accurately recover interpretable physical latent states and discover compact symbolic governing equations for nonlinear dynamical systems, outperforming black-box neural ODEs and classical identification methods across synthetic and real-world datasets.
This review surveys recent advances in using atomistic molecular dynamics simulations to characterize RNA conformational dynamics across various contexts, emphasizing the role of enhanced sampling, integrative approaches, and artificial intelligence in improving the precision and accuracy of structural ensembles.
This study challenges the prevailing hypothesis that rotational acceleration is the primary cause of concussion by demonstrating through direct in vivo measurements that linear acceleration is a significantly more precise predictor of injury, leading to the development of a liquid shock-absorbing helmet technology that could reduce concussion risk by up to 73%.
This paper investigates the localization transition of interacting particles in one-dimensional correlated disorder with vanishing backward scattering, using renormalization group methods and numerical simulations to demonstrate that the transition point shifts to the non-interacting limit and that the localization length scaling deviates from conventional behavior.
This paper develops a unified algebraic framework using moments to derive equilibrium equations for weighted point configurations with vanishing first moments, extending classical central configuration theory to arbitrary dimensions and mutual distances without relying on variational principles or isometric reductions.
This study estimates that the cumulative gravitational wave signal from recurring "peep" bursts of highly eccentric extreme mass ratio inspirals could either cause a minor increase in the LISA noise floor or, in more abundant scenarios, create a detectable background that significantly obscures other potential sources.
This paper proposes and rigorously establishes a symmetrization relation between 4d BPS quivers and 3d symmetric quivers, demonstrating that the wall-crossing structure of 4d Argyres-Douglas theories is isomorphic to the unlinking of their 3d counterparts and that these symmetric quivers successfully capture the Schur indices of the original 4d theories.
This paper presents a quadrature-based model reduction framework for Lagrangian hydrodynamics that utilizes a strongly energy-conservative variant of the empirical quadrature procedure to achieve near machine-precision total energy conservation while maintaining accuracy comparable to standard methods.
This paper attributes the performance degradation of GNN-based SAT solvers on difficult instances to inherent negative graph Ricci curvature in formula representations, which causes oversquashing by creating local connectivity bottlenecks that hinder the compression of long-range dependencies.
This paper reformulates the photon surface condition in spherical symmetry as a non-autonomous dynamical system to demonstrate its extension along null radial geodesics, applying this framework to a collapsing dust cloud to show that the photon surface uniquely continues as a null hypersurface into the interior spacetime, thereby enabling an analytical investigation of singularity coverage in the LTB model.
This paper introduces and analyzes a kinetic random-field nonreciprocal Ising model, revealing how the interplay between bimodal disorder and nonreciprocal interactions generates a nonequilibrium tricritical point that separates continuous Hopf and discontinuous saddle-node-of-limit-cycle transitions, while also uncovering a novel disorder-induced cyclic droplet phase.
This study employs advanced numerical and theoretical techniques to reveal that while spin-$1/2S=1, 3/2$) generalizations of the Majumdar--Ghosh chain exhibit prominent magnon modes and a universal phenomenon of spinon confinement into bound states across first-order phase transitions, thereby establishing a unified quasiparticle framework for understanding excitations in frustrated quantum spin chains.
This study reveals that the rupture of micron-thick liquid films is governed by a deterministic double-threshold mechanism requiring both sufficient outward driving force and cavity distortion, which explains why these films perforate despite molecular forces being negligible at that scale.
Using large-scale density matrix renormalization group simulations of the bosonic -- model, this study reveals six distinct quantum phases—including pair density waves and phase-separated ferromagnetic domains—arising from the competition between doped holes and antiferromagnetic order, while proposing a concrete experimental realization in Rydberg tweezer arrays to explore these intertwined orders relevant to high- superconductivity.
This paper establishes a central theorem that determines the necessary conditions on metric functions for the finiteness of all curvature invariants at the origin of static, spherically symmetric black holes, thereby defining the differentiability class and extendibility of such spacetimes in a model-independent, non-linear regime.
This study demonstrates that applying uniaxial strain to hexagonal -MnTe detwins its magnetic domains, thereby enabling precise control over the anomalous Hall effect, including the ability to reverse its sign near room temperature, by modifying the electronic Berry curvature without altering the material's altermagnetic phase-transition temperature.
