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.

A perturbative approach to the Wetterich equation for Bosonic and Fermionic interacting fields

This paper establishes a perturbative framework for the Lorentzian Wetterich Renormalization Group flow within perturbative Algebraic Quantum Field Theory on curved spacetimes, deriving beta functions for interacting scalar and Dirac fields, exploring connections to stochastic dynamics, and proving the local well-posedness of the resulting flow equations using the Nash-Moser theorem.

Higher Genus Gromov-Witten Theory of C^n/Z_n II: Crepant Resolution Correspondence

This paper establishes a higher genus crepant resolution correspondence between the Gromov-Witten theories of the canonical bundle KPn1K\mathbb{P}^{n-1} and the orbifold [Cn/Zn][\mathbb{C}^n/\mathbb{Z}_n] for arbitrary n3n \geq 3 by proving the finite generation of their potentials and constructing an isomorphism between their associated polynomial rings.

Data-driven stress problem under purely normal homogeneous Neumann boundary conditions

This paper establishes a rigorous functional-analytic framework for the data-driven stress problem under purely homogeneous normal Neumann boundary conditions, proving the existence and uniqueness of solution equivalence classes by leveraging the topological properties of the divergence operator and the proximinality induced by finite experimental data sets.

Alpha-Dependent Cross-Tidal Residuals Beyond the Diagonal Newtonian Lunar Tensor: A Halilsoy-Inspired 45{\deg} Eigenframe Channel

This paper proposes a testable, Halilsoy-inspired extension to the standard Newtonian lunar tidal model that introduces an alpha-dependent off-diagonal residual component, which rotates the tidal eigenframe and generates a distinct 45-degree cross-tidal signature absent in the classical diagonal tensor description.
