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.

Exact strong zero modes in quantum circuits and spin chains with non-diagonal boundary conditions

This paper constructs exact strong zero mode operators in integrable quantum circuits and the spin-1/2 XXZ chain with non-diagonal open boundary conditions that break bulk U(1) symmetry, demonstrating their role in inducing infinite boundary coherence times while showing they become spatially non-local and dynamically insignificant when mapped to the asymmetric simple exclusion process.

The Bianchi IX Attractor in Modified Gravity

This paper establishes that in specific modified gravity theories characterized by a parameter v(1/2,1)v \in (1/2, 1), all vacuum Bianchi type IX solutions converge to a Mixmaster attractor composed of Bianchi type I and II states, thereby proving an analogue of Ringström's theorem and demonstrating that, unlike in general relativity, no solutions converge to locally rotationally symmetric states.

Asymptotic non-Hermitian degeneracy phenomenon and its exactly solvable simulation

This paper explains the impossibility of regularizing intrinsic-exceptional-point singularities in non-Hermitian quantum models like the PT-symmetric imaginary cubic oscillator by constructing an exactly solvable finite-dimensional matrix toy model that mimics the asymptotic degeneracy of these systems while demonstrating that, unlike conventional exceptional points, such singularities cannot be resolved through small perturbations.
