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.

Differential system related to Krawtchouk polynomials: iterated regularisation and Painlevé equation

This paper establishes a connection between the recurrence coefficients of generalised Krawtchouk polynomials and the Painlevé V equation by demonstrating how iterative regularisation of their associated differential system yields polynomial systems and decompositions of birational transformations.

On the Spectral Geometry and Small Time Mass of Anderson Models on Planar Domains

This paper establishes small-time asymptotics for the Anderson Hamiltonian and parabolic Anderson model on bounded planar domains using probabilistic methods, demonstrating that a single observation of the system's eigenvalues or mass can almost surely recover geometric properties of the domain (such as area, boundary length, or fractal dimension) and the noise variance.

Tropicalized quantum field theory and global tropical sampling

This paper demonstrates that tropicalizing scalar quantum field theory yields an exact, non-linear recursion solution for the quantum effective action that enables a polynomial-time algorithm to sample moduli spaces of metric graphs, thereby proving that perturbative QFT computations lie in the polynomial-time complexity class and successfully evaluating the ϕ4\phi^4 beta function at 50 loops.

ff-bifbox: A scalable, open-source toolbox for bifurcation analysis of nonlinear PDEs

This paper introduces ff-bifbox, an open-source, scalable toolbox that integrates FreeFEM and PETSc to perform numerical branch tracing, stability analysis, and time integration for large, time-dependent nonlinear PDEs on adaptively refined 2D and 3D meshes, validated through novel results on the Brusselator, plate buckling, and compressible Navier-Stokes systems.

Rogue waves and large deviations for 2D pure gravity deep water waves

This paper rigorously characterizes the tail probability of rogue wave formation in 2D pure gravity deep water waves by proving that they most likely arise through dispersive focusing over optimal timescales, utilizing a novel method that combines normal forms and probabilistic techniques to propagate statistical information without requiring Gaussian approximations.
