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.

This paper develops a general theory of 3-dimensional orbifold completion by constructing a Morita category of -algebras within a Gray category with duals to describe generalized orbifolds and their defects in topological quantum field theories, thereby enabling the construction of universal state sum models and unifying recent results on Witt equivalent Reshetikhin–Turaev theories.
This paper classifies all Nijenhuis operators on 2-dimensional complex pre-Lie algebras and 3-dimensional complex associative algebras, utilizing these operators to derive solutions to the classical Yang-Baxter equation on their corresponding sub-adjacent Lie algebras.
This paper introduces a direct and explicit construction of a scalar pseudodifferential asymmetry operator of order $-3$ for the curl operator on a closed oriented Riemannian 3-manifold, which generalizes the classical eta invariant and encodes spectral asymmetry information through microlocal analysis.
This paper demonstrates that the Zernike system is equivalent to the Higgs oscillator on a sphere or pseudosphere, showing that its non-Hermitian nature is merely an artifact of an imaginary gauge that can be removed via a canonical transformation to reveal a Hermitian free particle system under specific parameter conditions.
This paper extends Kramers' law to bistable systems driven by fast chaotic dynamics rather than unbounded noise, demonstrating through a reduced-order AMOC model that this "chaotic Kramers' law" accurately predicts transition times and offers insights into recent AMOC collapses and recoveries observed in complex climate models.
This paper investigates the time-periodic flow of a thin viscous film on a rotating horizontal cylinder, revealing intricate fractal-like blow-up structures in the amplitude-frequency parameter space and demonstrating how asymptotic analysis in high- and low-frequency limits can delay overturning or construct stable quasi-periodic solutions.
This paper establishes the global regularity of Leray-Hopf weak solutions to the -dimensional Navier-Stokes equations for initial data in with by constructing a novel supercritical space and deriving viscosity-independent energy estimates through a re-scaling argument, thereby implying global solvability for the Euler equations.
This paper mathematically analyzes and confirms the existence of photonic band gaps near the low-dielectric light line in two-dimensional photonic crystal fibres, demonstrating their presence in both one-dimensional and ARROW fibre structures through asymptotic analysis without relying on specific dielectric contrast ratios or wave propagation constraints.
This paper presents a novel nonlinear projection-based model order reduction framework that utilizes Gaussian process regression and radial basis function interpolation to model closure errors in the latent space, offering improved efficiency, interpretability, and data efficiency compared to deep neural network approaches in complex fluid dynamics applications.
This paper establishes that weakly interacting quantum Hamiltonians exhibit uniform-in-temperature exponential decay of correlations and local indistinguishability by employing a low-temperature cluster expansion combined with a quantum probabilistic swapping trick.
