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.

Fusion rule in conformal field theories and topological orders: A unified view of correspondence and (fractional) supersymmetry and their relation to topological holography

This paper proposes a unified framework for ZNZ_N extended chiral and bulk conformal field theories and their corresponding topological orders by explicitly constructing a "bulk semion" subalgebra that elucidates the correspondence between fusion rules, generalized symmetries, and topological holography, thereby offering a method to derive topological order data directly from bulk CFTs.

Equivalent class of Emergent Single Weyl Fermion in 3d Topological States: gapless superconductors and superfluids Vs chiral fermions

This paper proposes a generic approach using spontaneous U(1)U(1) symmetry breaking to construct 3D lattice models that evade the no-go theorem and yield a single Weyl fermion in the infrared limit, demonstrating that these models form an equivalent class with gapless superconductors and superfluids across three distinct symmetry-breaking pathways.
