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.

On Gist.Science, we process every new preprint published in this category on arXiv to make these dense studies accessible to everyone. 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.

On Lagrangian formulations for (ir)reducible mixed-antisymmetric higher integer spin fields in Minkowski spaces

This paper extends Lagrangian formulations to construct gauge-invariant descriptions for (ir)reducible integer higher-spin massless and massive fields with mixed-antisymmetric symmetry in dd-dimensional Minkowski space using BRST methods, while also proposing a deformation procedure for their interacting models.

Boltzmann to Lindblad: Classical and Quantum Approaches to Out-of-Equilibrium Statistical Mechanics

This paper presents a unified framework that extends classical stochastic dynamics to the quantum domain by deriving a generalized Langevin equation with symmetric friction and noise, which upon quantization yields Lindblad-type master equations that ensure complete positivity and thermodynamic consistency for open quantum systems.

Effective dynamics and defect expansions for polynomial PDEs on thin annuli

This paper establishes a unified geometric and analytic framework using renormalized Sobolev orthogonal polynomials to derive stable dimension-reduction theorems and defect expansions for polynomial PDEs on thin annuli, effectively capturing their convergence to one-dimensional dynamics while accounting for anisotropic dispersive and homogenized effects across both integrable and non-integrable systems.

Symmetric Gapped States and Symmetry-Enforced Gaplessness in 3-dimension

This paper establishes a comprehensive framework in three spatial dimensions that classifies fermionic quantum anomalies into two distinct classes—those permitting symmetric gapped phases and those enforcing gaplessness—thereby providing concrete predictions for the infrared behavior of (3+1)-dimensional gauge theories and demonstrating that discrete chiral anomalies cannot be trivialized by adding bosonic degrees of freedom.

A Variational Formulation for Deformable Particle Simulations and its Level Set Discrete Element Method Implementation

This paper presents a computationally efficient deformable Discrete Element Method (DEM) that extends classical rigid-particle dynamics through an energetic variational formulation and level set evolution, enabling physically accurate grain-scale deformation for arbitrary particle geometries at a cost comparable to standard rigid DEM.
