Through high-field Rb NMR measurements on the triangular-lattice antiferromagnet RbNi(SeO), the study provides evidence for a magnetic up-up-down phase and two distinct gapless regimes consistent with spin supersolid phases, while revealing a unique negative slope in the UUD-V phase boundary driven by strong low-energy spin fluctuations.
This study utilizes high-fidelity direct numerical simulations to demonstrate that increasing inlet Mach numbers in a low-pressure turbine cascade systematically reduces separation bubble sizes and accelerates transition to turbulence, yet paradoxically increases profile losses by altering the transition pathway from spanwise rolls to streak-dominated bypass mechanisms.
This paper proposes a simple numerical method based on inverse transform sampling to efficiently load relativistic Maxwellian-type distributions by approximating the cumulative distribution of a shifted-Maxwellian energy distribution with an invertible function to generate random energy and momentum variates.
This study investigates the formation, motion, and interactions of topological defects in both the translational lattice and the geometrically frustrated spin states of vertically confined buckled colloidal monolayers, revealing how these defects drive grain boundary structures and spin domain coarsening to predict the system's material properties and aging.
This study demonstrates that consistently linearizing the eddy-viscosity turbulence model is essential for accurately capturing shape sensitivities of hydro-turbine vortex ropes, as neglecting these perturbations leads to incorrect sensitivity trends despite having minimal impact on the global mode's eigenvalues and eigenmodes.
This paper introduces Climate Downscaling with Stochastic Interpolants (CDSI), a cost-effective, data-driven method that leverages stochastic interpolants to efficiently transform coarse global climate model outputs into accurate high-resolution regional projections, thereby enabling broader ensemble simulations and improved uncertainty quantification compared to traditional Regional Climate Models.
This paper demonstrates that the Orthogonalizing Pseudopotential (OPP) method is equivalent to the singular limit of the Feshbach-Schur projection, providing a closed operator-level identity via the Schur complement that eliminates Pauli-forbidden states algebraically without relying on large auxiliary parameters.
This paper analyzes nuclear matter properties and neutron star structures using an extended linear sigma model, demonstrating that the introduction of the meson creates a plateau in symmetry energy consistent with experimental constraints, while a negative pion-nucleon sigma term is required to achieve a stiff equation of state capable of supporting massive neutron stars.
This paper resolves the phase diagram of the pyrochlore spin ice by mapping its monopole-free limit to 3D loop-gas models to classify topological sectors and demonstrate how thermal monopoles round phase transitions into continuous crossovers, a framework validated by classical Monte Carlo simulations.
This paper introduces a biologically plausible, two-phase quadratic integrate-and-fire neuron model that eliminates unphysical voltage divergence while retaining an exact, analytically tractable low-dimensional description for neuronal ensembles.
This paper demonstrates that linear response theory can break down in uniformly hyperbolic deterministic systems due to hierarchical asymmetry, where progressively finer transport channels activate at decreasing bias levels, causing effective mobility to diverge as the force approaches zero.
This paper presents the first systematic thermal analysis of tungsten-based plasma-facing components in the SPARC tokamak, evaluating damage characteristics like melt depth and vaporization losses caused by runaway electron beams during vertical displacement events.
This paper presents an explicit coordinate description of the dual cosmological polytope and derives its canonical form through two distinct triangulations based on maximal and almost maximal tubings of the underlying graph, the latter of which yields a novel expression for the form.
This paper investigates the thermodynamic indivisibility of quantum-corrected AdS black holes with regular or phantom global monopoles, finding that while monopoles generally prevent fragmentation due to negative entropy differences, significant quantum fluctuations or a sufficiently large AdS radius can induce black hole splitting under specific mass ratio conditions.
This paper investigates the classical translational dynamics of homonuclear diatomic molecules in a magnetic quadrupole trap, demonstrating through numerical and analytical methods that the system is non-integrable and exhibits chaotic behavior alongside periodic and quasi-periodic trajectories, with specific solutions expressible via Jacobi elliptic functions.
This paper establishes a unified canonical framework linking the Maximal Entropy Simple Symmetric Exclusion Process to both Unitary Dyson Brownian Motion and Free Unitary Brownian Motion by leveraging Schur polynomials and symmetric group characters to derive explicit spectral decompositions and hydrodynamic limits that reveal entropic forces and nonlinear transport equations.
This paper introduces a Fourier Neural Operator-based surrogate model that rapidly and accurately predicts angle- and energy-resolved proton transport and neutron production in proton therapy, achieving Monte Carlo-level accuracy within seconds to enable real-time adaptive range verification and neutron dose estimation.
This study demonstrates that interfacial hybridization, charge transfer, and strain serve as critical tuning parameters to control competing electronic phases in monolayer VSe, revealing that strong coupling to Au(111) suppresses the charge density wave (CDW) while strain in decoupled regions stabilizes a distinct CDW phase.
This review advocates for integrating biomechanical principles into hernia management by framing abdominal hernias as mechanical failures, thereby guiding the selection of surgical techniques and implants—such as lightweight retrorectus meshes and small-bite suturing—to better mimic native tissue properties and improve patient outcomes.
This paper constructs locally inertial and radially locked reference frames for geodesic observers in stationary axisymmetric dust spacetimes to analyze dust configurations via photon frequency shifts and establish a general relativistic framework for reconstructing spectroscopic and astrometric relative velocities in galactic kinematics.
