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 ODE/IM Correspondence between C(2)(2)C (2)^{(2)}-type Linear Problems and 2d N=1\mathcal{N} = 1 SCFT

This paper establishes the ODE/IM correspondence between the linear problem of the supersymmetric affine Toda field equation for the twisted affine Lie superalgebra C(2)(2)C(2)^{(2)} and 2d N=1\mathcal{N}=1 superconformal field theories by deriving WKB periods up to tenth order and verifying their agreement with the eigenvalues of local integrals of motion in the Neveu-Schwarz sector up to sixth order.

Static Tidal Perturbations of Relativistic Stars: Corrected Center Expansion and Love Numbers-I

This paper corrects the subleading coefficient in the regular-center Frobenius expansion for static tidal perturbations of relativistic stars and extends the even-parity master equation to Schwarzschild-de Sitter backgrounds, demonstrating that while the corrected coefficient alters initial data, it does not affect the extracted Love number k2k_2.

Computing the free energy of quantum Coulomb gases and molecules via quantum Gibbs sampling

This paper presents a mathematically rigorous quantum algorithm that estimates the free energy and Gibbs state of interacting quantum Coulomb gases and molecules in finite dimensions by combining finite-rank interaction truncation with a quantum Gibbs sampling scheme that guarantees exponential convergence via a strictly positive spectral gap.

bb-Hurwitz numbers from Whittaker vectors for W\mathcal{W}-algebras

This paper demonstrates that bb-Hurwitz numbers with rational weights arise as explicit limits of Whittaker vectors for type AA W\mathcal{W}-algebras, thereby generalizing previous results, providing a geometric interpretation via generalized branched coverings, and establishing that classical hypergeometric Hurwitz numbers are governed by Eynard-Orantin topological recursion.

Triviality vs perturbation theory: an analysis for mean-field φ4\varphi^4-theory in four dimensions

This paper establishes the connection between previously constructed non-perturbative mean-field trivial solutions of the four-dimensional O(N)O(N) φ4\varphi^4 theory and perturbation theory by demonstrating that, with an UV cutoff, the renormalized perturbation series is locally Borel-summable and asymptotic to the exact non-perturbative solution.
