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.

Whether you are a specialist or a curious reader, you will find both plain-language overviews and detailed technical summaries for each paper. Below are the latest mathematical physics papers from arXiv, curated to help you explore the cutting edge of theoretical science.

Bound States and Resonance Analysis of One-Dimensional Relativistic Parity-Symmetric Two Point Interactions

This paper investigates the scattering and confining properties, including bound states and resonances, of the one-dimensional Dirac equation with a general relativistic contact interaction supported on two symmetric points, utilizing a distributional method to analyze parity-symmetric configurations and their critical states.

A Globally Convergent Variational Framework for Mode Number Detection via Spectral Cutting Curves

This article proposes a globally convergent, variation-based framework that automatically determines the number of intrinsic mode functions in Variational Mode Decomposition by formulating spectral peak detection as an optimal curve-cutting problem, which is solved via a dual-ascent method for a fourth-order boundary value problem to provide a theoretically grounded initialization procedure.

A Total Lagrangian Finite Element Framework for Multibody Dynamics: Part I -- Formulation

This contribution presents a total Lagrangian finite element framework for multibody dynamics under large deformations that integrates a compact kinematic representation, a formulation based on the deformation gradient, and a systematic constraint methodology to model the equations of motion for assemblies of deformable bodies under various loads and material models.
