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.

Geometric Quantum Mechanics in a Symplectic Framework: Metric-Affine Extensions and Deformed Quantum Dynamics

This paper presents a geometric formulation of quantum mechanics that extends the standard Kähler framework by coupling the symplectic structure of projective Hilbert space to a metric-affine background, resulting in a mathematically consistent, deformed Hamiltonian dynamics where curvature and torsion induce specific corrections to quantum evolution and geometric phases.

Moment bounds and exclusion processes on random Delaunay triangulations with conductances

This paper establishes moment bounds for weighted degrees on random Delaunay triangulations derived from stationary point processes, demonstrating how these integrability properties ensure the well-definedness and key characteristics of symmetric simple exclusion processes while extending construction results to non-symmetric cases under specific dependence and boundedness conditions.

A qq-Caputo Fractional Generalization of Tsallis Entropy: Series Representation and Non-Negativity Domains

This paper introduces a fractional generalization of Tsallis entropy using the qq-Caputo operator to derive a closed series representation involving the qq-Gamma function, demonstrating that the standard entropy is recovered as the fractional order approaches one and analyzing the parameter domains where the resulting entropy remains non-negative.

Dirac Operators, APS Boundary Conditions, and Spectral Flow on a Finite Warped Cylinder

This paper investigates the Dirac operator on a finite warped cylinder with a U(1)U(1) gauge field by characterizing the APS boundary spectrum, demonstrating the vanishing of the APS index in the invertible constant-gauge case, and introducing a regularized self-adjoint boundary condition that ensures continuity across spectral crossings to enable a consistent spectral flow analysis within the Maslov framework.

Exact density-functional theory as parallel ensemble variational hierarchies: from Lieb's formulation to Kohn-Sham theory

This paper reorganizes exact density-functional theory into two parallel variational hierarchies rooted in Lieb's interacting and exact ensemble noninteracting formulations, clarifying their relationship to the Kohn-Sham construction and unifying concepts like fractional particle numbers and derivative discontinuities within a single framework.
