This paper demonstrates that short-ranged machine learned interatomic potentials (MLIPs) fail to capture long-ranged electrostatic interactions, leading to unphysical "false metallization" in polar solvents like water, a flaw that is resolved only by explicitly including long-range electrostatics.
This study demonstrates that including a dynamical charm quark and utilizing a mixed action setup yield light hadron properties consistent with standard 2+1 flavor calculations, with the mixed action's discretization errors potentially canceling out to improve continuum extrapolation convergence.
This paper presents a non-intrusive, multi-fidelity reduced-order modeling framework that utilizes Optimal Transport-based displacement interpolation to efficiently correct low-fidelity models and construct accurate parametric surrogates for complex, nonlinear two-phase flow simulations.
This paper presents a real-time 3D CMR-MOTUS method that enables continuous, beat-to-beat volumetric quantification of cardiac function in patients with arrhythmias, successfully overcoming motion artifacts to reveal functional heterogeneity and bimodal ejection fraction distributions obscured by conventional imaging techniques.
This study presents a grid-agnostic volume of fluid method for compressible multiphase flows that employs an ant-diffusive volumetric body force for interface sharpening and surface tension modeling, demonstrating accurate validation against analytical solutions and experimental data across various flow regimes.
This paper introduces a minimal kinetic model of dissipative hard disks with collision-induced chirality to derive nonlinear hydrodynamic equations and analytically predict odd transport coefficients, such as odd viscosity and thermal conductivity, which are validated by numerical simulations.
This chapter reviews the similarity renormalization group method for nuclear forces, detailing its flow equations, diagonalization mechanism, and induced many-body interactions to highlight its role in advancing first-principles nuclear calculations.
This paper demonstrates that single-minus tree-level -graviton scattering amplitudes are nonvanishing for specific kinematic configurations, deriving a Berends-Giele recursion relation that simplifies to a product of soft factors in a restricted decay region and reveals a connection to a recursive Ward identity.
This paper demonstrates that the common practice of maintaining a constant mean radius in wavy-walled tube models inadvertently increases interior volume, leading to significant discrepancies (up to 50%) in flow rate and hydraulic resistance compared to constant-volume models for both steady and peristaltic viscous flows, and provides a scaling law to relate these two cases.
This paper investigates the Casimir effect for a massive scalar field in a five-dimensional Lorentz-violating aether compactification, deriving closed-form expressions that reveal how the quasiperiodic parameter controls the transition between attractive and repulsive forces, while the Lorentz-violating parameter amplifies vacuum interactions and the compactification ratio stabilizes the system, particularly in high-compactification regimes.
This paper generalizes Backhausz and Szegedy's result on the infinite regular tree by proving that the Gaussian wave is the unique typical process with Green's function covariance for any infinite tree of finite cone type satisfying mild expansion, thereby establishing the convergence of local eigenvector distributions to the Gaussian wave for random bipartite biregular graphs and generic configuration models.
This paper reviews a collisional -model for vertically vibrated confined granular fluids, deriving hydrodynamic equations via kinetic theory that predict stable homogeneous states, energy nonequipartition in mixtures, and the violation of Onsager reciprocity, with theoretical results showing strong agreement with numerical simulations.
This study demonstrates that neutron stars can gravitationally confine ghost scalar fields with negative kinetic energy, supporting stable equilibrium configurations that evolve into persistent, synchronized oscillations between the stellar fluid and the scalar field.
