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.

The classical boundaries of the EPR argument and quantum ontology

This paper reformulates the quantum-classical transition by grounding classicality in the logical constraint of Booleanity rather than the dynamical limit, demonstrating that the EPR argument reveals inherent classical boundaries within quantum mechanics and proposing a new ontological framework that unifies objective phenomena with non-objective interference through a structural bipartition of observation.

Finite-Scale One-Component Regularity via Harmonic Pressure for the 3D Navier-Stokes Equations

This paper establishes a finite-scale one-component regularity mechanism for 3D Navier-Stokes suitable weak solutions by proving that smallness of the vertical velocity component yields a positive local regularity radius through harmonic pressure approximation, while further offering conditional logarithmic and power-type refinements via two-shadow and relaxed-shadowing comparison techniques.

Microscopic universal theory of symmetry-enriched topological quantum spin liquids

This paper presents a comprehensive microscopic universal theory for symmetry-enriched topological quantum spin liquids that utilizes measurable microscopical quantities to characterize their universal properties, establishes a precise crystalline equivalence principle via a bijective map between lattice and internal symmetry data, and validates the framework through demonstrations on various quantum hardware platforms.
