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.

Central limit theorems for non-linear functionals of Gaussian fields via Wiener chaos decomposition

This paper establishes a Central Limit Theorem for non-linear functionals of discrete Gaussian fields on the dd-dimensional lattice using Wiener chaos decomposition and the fourth moment theorem, demonstrating that even powers of the discrete Gaussian Free Field converge to Gaussian white noise while odd powers converge to a continuous Gaussian Free Field with explicit covariance.

Electrical networks, Grassmannians, and cluster algebras

This paper establishes deep connections between electrical networks, Grassmannians, and cluster algebras by constructing a specific seed in Scott's cluster algebra on Gr(n1,2n)\mathrm{Gr}(n-1,2n) to relate circular total positivity to Grassmannian positivity, and by proving that the Laurent Phenomenon algebra LMn\mathcal{LM}_n is isomorphic to the coordinate ring of the space of electrical networks.

Geometric Universality and Thermodynamic Microstructure of Real Fluids in a Unified Entropic Framework

This paper proposes a unified entropic framework for real fluids that utilizes Geometrothermodynamics to link macroscopic critical phenomena and intermolecular force balances to the scalar curvature of the equilibrium manifold, while introducing universal dimensionless ratios and Bayesian statistical methods to characterize and validate the geometric scaling behavior across different equations of state.

Global existence and optimal decay for a three-dimensional penalized Navier--Stokes system with biharmonic damping

This paper establishes the global existence and optimal large-time decay rates for weak and strong solutions of a three-dimensional penalized Navier--Stokes system featuring biharmonic damping and a Temam-type correction, while proving that all derived a priori estimates remain uniform with respect to the penalization parameter.

Higher-order interactions for controlling time-delayed Kuramoto model

This paper proposes a delay-free, higher-order approximation framework for the time-delayed Kuramoto model that, through analytical reduction and numerical validation, enables more accurate prediction of collective dynamics and the control of complex states like bistability and intermediate synchronization compared to conventional pairwise approaches.
