This paper details the first calculation of the effective source required for second-order gravitational self-force computations on quasicircular orbits in Schwarzschild spacetime, validating its various components through analytical and numerical tests to support post-adiabatic gravitational-waveform modeling.
This paper proposes an accurate and memory-efficient sum-of-Gaussians tensor neural network (SOG-TNN) algorithm that overcomes the curse of dimensionality and handles Coulomb singularities in high-dimensional Schrödinger equations through a low-rank tensor representation and a novel range-splitting scheme for electron-electron interactions.
This paper presents a dynamical method for measuring the saturation vapor pressures and enthalpies of vaporization of low-volatility liquids across an extended temperature range of -10 to 35°C, validated through experiments on four reference substances.
This paper presents a thermodynamically consistent coarse-graining framework based on Doi-Peliti field theory that maps interacting particles to exact field theories, revealing how Poissonian statistics and noise effects govern distinct phase transition behaviors in low- and high-density regimes of the active Ising model.
This study reveals that defect creation and annihilation in diverse active living systems exhibit spatial symmetry breaking and irreversibility driven by a dualism between nematic structure and polar forces, challenging conventional active nematic theories and highlighting these processes as major sources of entropy production.
This study establishes a systematic gigantic-oxidative atomic-layer-by-layer epitaxy approach to grow phase-pure, high-quality Ln3Ni2O7 thin films that exhibit superconductivity with an onset transition temperature of 50 K without post-annealing, while identifying four critical factors—precise cation stoichiometry, complete atomic layer coverage, optimized interface reconstruction, and accurate oxygen content regulation—that govern their crystalline quality and superconducting properties.
This paper extends a theoretical model of wave attenuation through broken floating ice of random thickness to finite water depths, utilizing multiple scales analysis to derive an explicit attenuation expression that predicts an eighth-power frequency dependence at low frequencies and shows strong agreement with numerical simulations and field measurements.
This paper proposes a novel quasi-topological gravity model that unifies cosmological and black hole scenarios by replacing spacetime singularities with a "big bounce" and a "black bounce," respectively, thereby reproducing key results from loop quantum cosmology and the quantum Oppenheimer-Snyder model within a single, manifestly covariant framework.
This paper introduces a reduction method for Boolean networks based on dominant vertices, proving that the induced dynamics on these vertices are asymptotically equivalent to the original system, thereby simplifying the analysis of attractors, basins, and transient behaviors.
This paper reports the fabrication of boron-doped, ultra-thin carbon nanotube networks within zeolite pores that exhibit characteristic signatures of high-temperature superconductivity with a critical temperature between 220 and 250 K, alongside a giant pressure effect that further elevates this transition temperature.
This paper investigates the existence and form of Onsager-Machlup functionals for measures in dimensions , demonstrating that they recover the standard action in one and two dimensions (using enhanced distances) while proving degeneracy in three dimensions unless specific joint limits are considered.
This paper investigates the causal structure and interior geometry of asymptotically AdS black holes containing vacuum bubbles by analyzing holographic entanglement entropy and bulk-cone singularities, revealing that while collapsing and expanding bubbles exhibit thermalization, static bubbles display non-thermal "scar state" properties.
This paper demonstrates through numerical simulations that a self-propelled two-dimensional elastic sheet exhibits hallmark features of turbulent dynamics, such as power-law energy scaling and non-Gaussian velocity statistics, thereby extending the concept of active turbulence to solid-state active matter like bacterial colonies and epithelial cell layers.
This paper presents a new formulation of extended lubrication theory and demonstrates through comparison with existing models and numerical Stokes solutions that its accuracy depends significantly on surface variation magnitude and length scale ratio, making it suitable for a wide range of fluid domain geometries.
This paper analyzes the spatiotemporal stability of synchronized states in coupled map lattices by performing a linear stability analysis of the orbit Jacobian in reciprocal space to determine how coupling strength influences stability against both periodic and incoherent perturbations.
This paper presents a Hybrid High-Order (HHO) formulation for variable density incompressible flows that ensures exact volume conservation and pure density advection through a combination of hybrid spatial discretization and ESDIRK time stepping, demonstrating robustness, pressure-independence, and high-order accuracy in simulating immiscible fluid mixtures and Rayleigh-Taylor instabilities.
This paper generalizes Carrollian Lie algebroids to the framework of -commutative (almost commutative) geometry via -Lie-Rinehart pairs, establishing foundational analogues for Carrollian structures and demonstrating their application through explicit constructions on the extended quantum plane and the noncommutative 2-torus.
This paper demonstrates that incorporating quantum fluctuations via Jackiw-Teitelboim (JT) gravity in a holographic model of near-extremal black branes generates a non-universal, temperature-dependent shear viscosity to entropy ratio () that dips below the KSS bound in the semi-classical regime before rising above it at lower temperatures, a result that aligns with the quantum-corrected absorption cross-section.
This paper proposes a computationally efficient chaos indicator based on the norm of the tangent map derived via automatic differentiation to accelerate dynamic aperture optimization, as demonstrated in the ALS-U lattice design.
This paper presents a simplified Standard Model plus gravity framework featuring left and right mirror sectors that share and gravitational fields to cancel anomalies, interprets the right sector as dark matter, and explores the cosmological and quantum implications of Weyl symmetry, including potential solutions to the cosmological constant problem and the avoidance of negative norm states.
