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.

Perturbative Approach to Nonlinear Capacitance Matrix Formulations

This paper establishes a rigorous, algorithmic perturbative framework that creates a two-way correspondence between a continuous nonlinear Helmholtz system with high-contrast inclusions and a discrete nonlinear capacitance matrix, enabling the expansion of resonant frequencies and fields in powers of the contrast parameter to characterize solitons and symmetry-breaking bifurcations.

Geometric numerical discretization of a quasineutral hybrid model of drift-kinetic electrons and fully kinetic ions

This paper extends the geometric electromagnetic particle-in-cell framework (GEMPICX) to solve quasineutral hybrid Vlasov-Maxwell equations with drift-kinetic electrons and fully kinetic ions by deriving a discrete action principle, employing a structure-preserving finite difference method on dual grids, and validating the resulting numerical model through dispersion relation analysis.

Digital Beam Pattern Optimisation for the GRAO 32-m Telescope: A Comparative Analysis of FIR Filter Design Methods

This paper presents a digital signal processing framework that adapts finite-impulse-response (FIR) filter design methods to optimize the beam pattern of the 32-m Ghana Radio Astronomy Observatory telescope, successfully suppressing sidelobes and cross-polar leakage to enhance its polarimetric precision and suitability for high-dynamic-range radio astronomy applications.

Geometric Structures of Pseudo-Sonic Curves in Self-Similar Solutions of the Euler Equations for Potential Flow

This paper rigorously analyzes the geometric structures of pseudo-sonic curves in two-dimensional self-similar solutions of the Euler equations for potential flow, proving that these curves are necessarily circular arcs under specific conditions and establishing C2,αC^{2,\alpha} regularity for shock reflection-diffraction problems with non-uniform incoming flows.
