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.

Do quantum linear solvers offer advantage for networks-based system of linear equations?

This exploratory numerical study evaluates the potential for quantum advantage in solving network-based linear systems by analyzing 50 graph families across multiple quantum algorithms, identifying specific "good" families that offer exponential speedups over classical solvers, and proposing visual conjectures to predict these advantages while acknowledging practical hardware limitations.

Characterizing the Kirkwood-Dirac positivity on second countable LCA groups

This paper extends the characterization of Kirkwood-Dirac positivity to second countable locally compact abelian groups by linking the representation to Kohn-Nirenberg quantization, identifying positive pure states as Haar measures on closed subgroups, and establishing that the associated classical fragment is non-trivial if and only if the group possesses a compact identity component.
