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.

Emergence of Tsallis Statistics from a Self-Referential Nonlinear Operator: A Variational Framework

This paper establishes an operator-theoretic foundation for nonextensive statistical mechanics by demonstrating that a variational framework based on a self-referential nonlinear operator naturally yields Tsallis statistics in the mean-field limit, with the entropic index qq emerging directly from the operator's structural exponents rather than being postulated.

Hydrodynamics and boundary-induced phase transitions in the nn-species particle-exchange process

This paper investigates the hydrodynamic behavior of the nn-species particle-exchange process, deriving explicit solutions for its coupled inviscid Burgers equations and characterizing the stationary phase diagram of the open system, which exhibits 2n+12n+1 boundary-induced phases analogous to the single-species asymmetric simple exclusion process.

Characterizing bulk properties of gapped phases by smeared boundary conformal field theories: Role of duality in unusual ordering

This paper proposes a framework using smeared boundary conformal field theories to characterize gapped phases and massive renormalization group flows dual to massless ones, revealing that such phases often involve unphysical smeared Ishibashi states and spontaneously break non-invertible symmetries, thereby providing a quantum field-theoretic description of unusual order-disorder coexistence.

Hamiltonian formulation of the supersymmetric KdV equation

This paper presents a constrained Hamiltonian formulation of a specific supersymmetric KdV equation (with parameter a=2a=2) using the Dirac-Bergmann algorithm, revealing a unique nonlocal contribution to the Hamiltonian density arising from fermionic consistency conditions and demonstrating the equivalence between the derived Hamiltonian dynamics and the component-form supersymmetric KdV system.
