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 contraction theory for universal -matrices of quantum groups to derive a new (1+1) centrally extended quantum Poincaré algebra whose dual form naturally describes relativistic quantum reference frame transformations and contracts to the known Galilei -matrix for non-relativistic frames.
This paper establishes that for almost all symmetric spaces, the joint eigenfunctions of invariant differential operators on a sequence of compact locally symmetric spaces converging in the Benjamini--Schramm sense delocalize on average, provided the sequence is uniformly discrete, possesses a uniform spectral gap, and the spectral parameters lie within a fixed window.
This paper establishes a rigorous and implementable framework for Gibbs sampling in infinite-dimensional quantum systems with unbounded Hamiltonians by constructing KMS-symmetric quantum Markov semigroups based on Dirichlet forms, which enables efficient circuit implementation on qubit hardware while providing quantitative convergence guarantees and revealing a fundamental trade-off between implementability and convergence.
This paper proves Griffiths inequalities for the -spin model with inhomogeneous couplings and external magnetic fields for any by utilizing a random path representation and an identity analogous to the switching lemma for random currents.
This paper constructs 3+1D and 2+1D Hamiltonian lattice models for Weyl fermions and Dirac cones that evade no-go theorems by utilizing exact, not-on-site chiral symmetries—specifically a Ginsparg-Wilson analog and an Onsager algebra—to protect gaplessness and generate global anomalies even in the absence of crystalline translations.
This paper establishes a quantum energy inequality for non-commutative quantum field theories by constructing deformed operator combinations that provide a rigorous lower bound on averaged energy density, thereby ensuring the theory's stability and physical consistency.
This paper introduces a Homothetic Gauge Theory based on a Homothetic Hodge de Rham framework, which utilizes a dilaton field to generate scale-covariant interactions that successfully regularize the divergent self-energy of a point charge, rendering both its electric field and total energy finite at the origin.
This paper formalizes a classification of three distinct types of local parent Hamiltonians that share a given quantum state as an exact eigenstate, rigorously deriving the complete set of such Hamiltonians for the state to reveal its role as a Quantum Many-Body Scar and establishing general constraints for product and short-range-entangled states.
This paper establishes a rigorous formulation of umbral theory within the context of formal power series with complex coefficients by defining the umbral operator on a subalgebra of analytically convergent series, utilizing Gevrey classification and Borel-Laplace resummation to validate divergent identities, and applying this framework to introduce new Gaussian trigonometric functions and a "Gaussian Fourier transform."
This paper simplifies the calculation of group character averages in a Gaussian matrix model by deriving generic sum rules that express arbitrary traces as convolutions of a single Laguerre polynomial, despite the complexities introduced by extended Laguerre polynomials in the matrix entries.
