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.

Diffusion in multi-dimensional solids using Forman's combinatorial differential forms

This paper extends Forman's combinatorial differential forms to model physical diffusion processes in multi-dimensional solids by introducing an intrinsic framework that operates on cells of varying dimensions without assuming smooth vector fields, thereby enabling the simulation of how microstructural property changes affect macroscopic behavior.

Kirillov's conjecture on Hecke-Grothendieck polynomials

This paper utilizes algebraic methods from statistical mechanics to represent Kirillov's multi-parameter class of polynomials—including Schubert and Grothendieck polynomials—as partition functions of solvable lattice models, thereby proving positivity conjectures for Hecke-Grothendieck polynomials while revealing that the broader family can exhibit negative coefficients.

Macroscopic Particle Transport in Dissipative Long-Range Bosonic Systems

This paper establishes a generalized optimal transport theory for dissipative long-range bosonic systems, revealing that while one-body and multi-body losses fundamentally alter maximal transport speeds and distances, the presence of even minimal gain or decoherence-free subspaces can enable long-distance, perfect particle transport, with derived bounds on transport probability guiding future experimental protocols.
