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.

How characterisations of traces and central elements fail: sharp violation constants via michelson contrast and noncentrality

This paper quantifies the sharp violation constants for various characterisations of traces and central elements in matrix algebras and finite von Neumann algebras, demonstrating that these constants are governed by Michelson contrast and noncentrality parameters respectively, with exact values derived for numerous inequalities including Gardner's inequality and the Novikov-Tikhonov characterisations.

Magnetic billiards:duality and magnetic Radon property

This paper investigates Birkhoff magnetic billiards in constant weak magnetic fields by establishing the existence of a functional family of centrally-symmetric convex tables with the magnetic Radon property via topological arguments, while proving that tables with discrete rotational symmetry admit invariant curves of periodic orbits only if they are circular, all supported by newly developed tools including magnetic duality and generating functions for outer magnetic billiards.

Path space large deviation on a lattice for interacting particle systems

This paper establishes a path space large deviation principle for interacting particle systems on a finite lattice, identifying the rate function as the Legendre transform of a nonlinear Hamiltonian through martingale techniques and exponential tilting, while demonstrating the framework's applicability to diverse models ranging from partial exclusion processes to continuous-state energy-exchange systems.
