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.

Double-scaled SYK from boundary metrics of planar maps

This paper demonstrates that for a specific family of bipartite planar maps with q-deformed face weights arising from the double-scaled SYK model, the weighted enumeration of maps with a fixed boundary metric depends solely on the crossing number of the associated geodesic chord diagram, thereby establishing an exact correspondence between the induced law of these diagrams and the chord diagram representation of the DSSYK model.

Subspace Selected Variational Quantum Configuration Interaction with a Partial Walsh Series

This paper proposes a subspace-selected variational quantum configuration interaction algorithm that utilizes subspace superposition and diagonal Walsh operators to efficiently compute exact and near-exact electronic ground-state energies for arbitrary Hamiltonians while bypassing costly classical matrix diagonalizations.
