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.

Below are the latest mathematical physics papers from arXiv, curated to help you explore the cutting edge of theoretical science.

Modelling Capillary Rise with a Slip Boundary Condition: Well-posedness and Long-time Dynamics of Solutions to Washburn's Equation

This paper extends Washburn's capillary rise equation by incorporating a slip boundary condition, proving the global well-posedness of the resulting initial-value problem and characterizing the long-time dynamics, including monotonic or oscillatory convergence to equilibrium, for a wide range of slip parameters and initial fluid heights.

Spectral moments of complex and symplectic non-Hermitian random matrices

This paper establishes a unifying framework for calculating mixed spectral moments of complex and symplectic non-Hermitian random matrices by deriving explicit formulas based on orthogonal polynomial norms, demonstrating their structural parallels to Hermitian limits, and performing large-NN asymptotic analyses for specific ensembles like the elliptic Ginibre and non-Hermitian Wishart matrices.

Quantum recurrences and the arithmetic of Floquet dynamics

This paper establishes an arithmetic framework based on algebraic field theory and cyclotomic structures to rigorously determine exact, state-independent recurrence times in finite-dimensional Floquet systems, revealing that rational Hamiltonian parameters do not guarantee recurrence and providing efficient methods to identify or rule out such dynamics across both integrable and non-integrable models.

Electromagnetic wave propagation in static black hole spacetimes: an effective refractive index description in Schwarzschild geometry

This paper presents a fully covariant and gauge-invariant formulation of electromagnetic wave propagation in static black hole spacetimes that reduces both axial and polar sectors to a unified master equation, enabling the derivation of a closed-form, position- and frequency-dependent effective refractive index in Schwarzschild geometry to provide an intuitive optical framework for analyzing gravitational effects on wave dynamics.
