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.

Linear statistics in the Coulomb gas: cumulants beyond rotational invariance

This paper derives explicit formulas for the leading third and fourth cumulants of smooth linear statistics in a general dd-dimensional Coulomb gas by utilizing shape derivatives of the Dirichlet energy and the deformation of the equilibrium droplet, thereby extending previous two-dimensional radial results to non-radial settings and providing rigorous proofs for specific cases.

Spatial symmetry invariance of three-dimensional Navier-Stokes turbulence

This paper proves a spatial symmetry invariance theorem for three-dimensional Navier-Stokes equations, demonstrating that traditional Direct Numerical Simulations fail to preserve this symmetry due to numerical noise rather than physical instability, thereby challenging the ergodicity assumption in turbulence theory and revealing fundamental flaws in current computational fluid dynamics benchmarks.

Admissible Subspaces for the Collective Haar Twirl: Schur-Weyl Classification and Heredity under Tensor-Factor Reduction

This paper utilizes Schur-Weyl duality to fully classify the subspaces within tensor-power spaces that support quantum private broadcasting by identifying conditions under which the collective Haar twirl acts as a replacement channel, while also characterizing how privacy and design properties are preserved when reducing the number of recipients.

Φ34Φ^4_3 measures on compact Riemannian $3$-manifolds

This paper constructs the nontrivial, isometry-covariant Φ34\Phi^4_3 measure on arbitrary compact 3-dimensional Riemannian manifolds as an invariant probability measure of a singular stochastic partial differential equation, utilizing a novel renormalization approach based on microlocal and harmonic analysis to derive universal constants independent of the manifold geometry.
