Mathematical physics sits at the fascinating intersection where abstract equations meet the fundamental laws of our universe. This field uses rigorous mathematical tools to model everything from the behavior of subatomic particles to the curvature of spacetime, turning complex theories into testable predictions. It is the language through which physicists describe reality, bridging the gap between pure mathematics and physical observation.

Below are the latest mathematical physics papers from arXiv, curated to help you explore the cutting edge of theoretical science.

A generalized fundamental solution technique for the regularized 13-moment system in rarefied gas flows

This paper proposes and validates a generalized method of fundamental solutions (MFS) for the regularized 13-moment equations in rarefied gas flows, demonstrating its superior convergence and efficiency over the finite element method through applications to both analytical and thermally-induced non-coaxial cylinder flow problems.

Universality of global asymptotics of Jack-deformed random Young diagrams at varying temperatures

This paper establishes universal formulas for the global asymptotics of Jack-deformed random Young diagrams across high, low, and fixed temperature regimes, proving limit laws for Jack–Thoma measures and demonstrating that these results apply universally to models with approximate factorization while revealing that their limit shapes are one-sided infinite staircases distinct from continuous β\beta-ensembles.

Gravitating vortices and Symplectic Reduction by Stages

This paper introduces a novel symplectic reduction by stages approach to the existence problem for gravitating vortices on Riemann surfaces, utilizing the reduced α\alpha-K-energy and finite-energy pluripotential theory to establish polystability conditions for solutions on the sphere, prove uniqueness in the absence of automorphisms, and demonstrate existence for genus g1g \geq 1 under specific parameter constraints.

Extensions to the Navier-Stokes-Fourier Equations for Rarefied Transport: Variational Multiscale Moment Methods for the Boltzmann Equation

This paper presents a novel fourth-order entropy-stable extension of the Navier-Stokes-Fourier equations for rarefied gases, derived via a new variational multiscale moment closure of the Boltzmann equation that demonstrates remarkable accuracy in the transition regime and beyond when validated against linearized Boltzmann solutions.

Symdyn\texttt{Symdyn}: an automated algebraic solution for high-order quantum systems

This paper introduces Symdyn\texttt{Symdyn}, an automated Python library that implements the Wei-Norman method to efficiently derive time evolution operators for high-order quantum systems governed by Lie algebra Hamiltonians, demonstrated through applications to coupled harmonic oscillators and various SU(N)\textit{SU}(N) groups relevant to quantum computing.
