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.

High-Accuracy Semi-Analytical Method for Solving the Problem of Electromagnetic Wave Scattering by Arbitrary Ensembles of Parallel Circular Cylinders

This paper proposes a high-accuracy semi-analytical method based on cylindrical harmonic expansions and Graf's addition theorem to solve the two-dimensional electromagnetic wave scattering problem for arbitrary ensembles of parallel circular cylinders, enabling numerically verified solutions with controlled precision even for densely packed subwavelength configurations.

Operator-theoretic approach to the partial integration of randomly coupled phase oscillators

This paper constructs a partially integrable Kuramoto model on a random graph of specific network motifs and demonstrates its partial integration by deriving conserved quantities and an operator-theoretic Watanabe-Strogatz transformation using Koopman theory, Magnus expansion, and the Baker-Campbell-Hausdorff formula.

Van Vleck spectra of high-order Heun operators:\ finite-band universality and exterior asymptotics

This paper establishes the finite-band universality and exterior asymptotics of high-order Heun operators by deriving a determinant representation for their spectral polynomials, proving that the weak limits of their roots depend solely on the leading coefficient, and providing explicit Picard–Fuchs equations and a mother-body conjecture for the resulting spectral measures.

Higher order Weyl coefficients for the operator curl

This paper establishes refined spectral asymptotics for the curl operator on a closed Riemannian 3-manifold by deriving explicit formulae for the first six global and local Weyl coefficients, proving the holomorphy of the eta function in the half-plane Res>2\operatorname{Re}s>-2, and improving Bär's counting function remainder to o(λ2)o(\lambda^2) under specific geodesic flow assumptions.
