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.

Hamilton--Jacobi theory for non-conservative field theories in the kk-contact framework

This paper establishes a comprehensive Hamilton–Jacobi theory for non-conservative classical field theories within the kk-contact framework by introducing evolution kk-contact kk-vector fields, developing both zz-independent and zz-dependent approaches, and validating the formalism through diverse applications ranging from dissipative wave equations to relativistic thermodynamics.

BV quantization of ϕ3\phi^3-theory on λ\lambda-Minkowski space: Tree-level correlation functions

This paper reviews the Batalin–Vilkovisky quantization of ϕ3\phi^3-theory on λ\lambda-Minkowski space by comparing standard and braided approaches, demonstrating that while standard quantization produces two inequivalent classes of tree-level diagrams with distinct noncommutative contributions, braided quantization yields a single class of diagrams where noncommutativity manifests only as an overall phase factor dependent on external momenta.

Brown measures of deformed LL^\infty-valued circular elements

This paper provides a comprehensive classification of the edge singularities and interior zeros of the Brown measure for deformed B\mathcal{B}-valued circular elements, establishing that the measure possesses a real-analytic density with specific jump discontinuities at the spectral boundary and demonstrating that all identified singularity types are realizable in the context of large non-Hermitian random matrices.
