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.

Distinct Types of Parent Hamiltonians for Quantum States: Insights from the WW State as a Quantum Many-Body Scar

This paper formalizes a classification of three distinct types of local parent Hamiltonians that share a given quantum state as an exact eigenstate, rigorously deriving the complete set of such Hamiltonians for the WW state to reveal its role as a Quantum Many-Body Scar and establishing general constraints for product and short-range-entangled states.

Umbral theory and the algebra of formal power series

This paper establishes a rigorous formulation of umbral theory within the context of formal power series with complex coefficients by defining the umbral operator on a subalgebra of analytically convergent series, utilizing Gevrey classification and Borel-Laplace resummation to validate divergent identities, and applying this framework to introduce new Gaussian trigonometric functions and a "Gaussian Fourier transform."
