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.

Non-equilibrium modelling of polyatomic gases: generic framework and 11-moment model

This paper presents a thermodynamically consistent framework for modelling polyatomic gases by integrating the GENERIC formalism with an 11-moment description to unify rational and extended irreversible thermodynamics, ensuring second-law compliance and validating the model against DSMC simulations and experiments for shock wave structures in nitrogen.

Decoupling candidate dual AGN from chance superpositions in the GOTHIC survey via a deep-learning framework

This paper presents a deep-learning framework based on YOLOv11 that re-analyzes rejected GOTHIC survey candidates to distinguish genuine dual active galactic nuclei from chance superpositions, yielding a refined catalogue of approximately 13,672 to 29,605 plausible systems that significantly reduces contamination and expands the census of merging supermassive black holes.
