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.

Dipole Formation in the Two-Component Plasma

This paper establishes that in a two-dimensional two-component plasma with logarithmic interaction, charges predominantly form neutral dipoles as the regularization scale vanishes for inverse temperatures β≥2\beta \geq 2, thereby confirming a phase transition at β=2\beta = 2 from free charges to dipole pairs through a novel energy analysis based on nearest-neighbor graphs and electric reformulations.

Large-Level Limit of Doubled Chern-Simons Theory Part I: Regular Sector, Boundaries and Interfaces

This paper investigates the large-level limit of doubled Chern-Simons theory as a bridge to three-dimensional BFBF theory, demonstrating that regular torus states and modular transformations converge to their BFBF counterparts while characterizing the resulting boundary theories and gapped interfaces.

A vertex operator algebra for the S-fold realisation of a non-unitary Haagerup--Izumi modular fusion category

The paper demonstrates the existence of a strongly rational vertex operator algebra V11V_{11} whose representation theory is equivalent to the braided category formed by the tensor product of the semion category and the Galois-twisted center of Ostrik's Haagerup category, thereby providing a vertex operator algebra realization for a non-unitary Haagerup–Izumi modular fusion category.

Smooth Quasi--Einstein Lifts of Locally Embeddable Three-Dimensional CR Manifolds

This paper establishes that every smooth, locally CR-embeddable, strictly pseudoconvex three-dimensional CR manifold admits a local smooth Lorentzian quasi-Einstein lift with specific geometric properties for any real cosmological constant, thereby extending previous lifting theorems beyond the real-analytic and Sasakian settings through a proof combining L∞L^\infty contraction and subelliptic regularity.
