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.

RG Limit Cycles in BKT Flows ≡\equiv Periodic Real-Time Dynamics in the Current-Current Perturbed SU(2)1SU(2)_1 WZW Model

This paper establishes an exact correspondence between renormalization-group limit cycles in the anisotropic current-current perturbed SU(2)1SU(2)_1 WZW model and periodic real-time dynamics of its interaction strengths, demonstrating that the Berezinskii-Kosterlitz-Thouless RG flow equations emerge from the consistency conditions of quantum Knizhnik-Zamolodchikov equations derived via the generalized Bethe ansatz.

Global synchronization of topological signals with time-delayed interactions

This paper investigates how time-delayed interactions affect the global synchronization of topological oscillators on higher-order structures, deriving analytical conditions via the Master Stability Function and Lambert W-function to show that while delays can either promote or suppress synchronization for signals coupled through the Hodge-Laplace matrix, global synchronization is impossible for signals of different dimensions coupled by the Dirac operator.

Infinite-Particle Determinantal Dynamics from Brownian Motion on GLN(C)\mathrm{GL}_N(\mathbb{C})

This paper establishes that the edge scaling limit of the logarithms of squared singular values for multiplicative Brownian motion on GLN(C)\mathrm{GL}_N(\mathbb{C}) yields infinite-particle determinantal dynamics with an explicit double-contour correlation kernel, where the dependence on arbitrary initial conditions (including coinciding coordinates) is encoded by Laguerre–Pólya entire functions.
