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.

Reconstructability of Inverse Problems under Symmetry: Separating Structural, Effective, and Physical Upper Bounds

This paper introduces a three-level hierarchy of upper bounds—Structural, Effective, and Physical Reconstruction Dimensions—to distinguish between the theoretical limits of reconstructability imposed by symmetry, the constraints of specific reconstruction maps, and the degeneracies inherent in physical processes, thereby providing a framework to identify where information is lost in inverse problems.

Asymmetric phase transitions in random noncommutative geometries

This paper investigates asymmetric phase transitions in random noncommutative geometries by employing the Riemann-Hilbert approach, bootstrapping with positivity, and Hamiltonian Monte Carlo simulations to derive explicit formulae and reconstruct the intricate phase structure of quartic (0, 1) and (1, 0) Dirac ensembles, with all three methods demonstrating excellent agreement for large matrix sizes.

Factorization method for a clamped obstacle from near-field measurements via a far-field transformation

This paper proposes a factorization method for reconstructing an unknown clamped obstacle from near-field measurements of the biharmonic Helmholtz equation by introducing an obstacle-independent far-field transformation that enables a symmetric factorization of the operator, thereby providing a rigorous characterization and a practical spectral reconstruction algorithm.
