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.

Higher-order transformations of bidirectional quantum processes

This paper characterizes the most general forms of input-output indefiniteness in bidirectional quantum devices by establishing a hierarchy of higher-order transformations built from bistochastic channels, which encompasses both indefinite local directions and indefinite global causal orders within a time-symmetric quantum framework.

Regularization for Multi-Phase 2D Euler Equations via Competing Transport Markers

This paper introduces a novel regularization framework for the 2D incompressible Euler equations that preserves multi-phase transport structures through competing scalar markers, proving that the scheme converges to sharp vortex patch solutions as the sharpness parameter increases, with convergence failure precisely signaling the onset of geometric degeneracy in the interface dynamics.

Spectral Analysis of Brownian Motion with its Rheological Analogues

This paper establishes a viscous viscoelastic correspondence principle demonstrating that the power spectrum of Brownian motion in linear viscoelastic materials is proportional to the real part of the complex dynamic fluidity of a rheological network combining the material with an inerter, thereby simplifying spectral calculations for diverse systems like Maxwell fluids and subdiffusive media.

Antiferromagnetic domain walls under spin-orbit torque

This paper theoretically investigates the tunable dynamical behaviors of antiferromagnetic domain walls under spin-polarized currents, revealing distinct regimes of precessional, propagating, and oscillatory motion depending on current polarization, characterizing their velocity and asymmetric profiles, and discussing the impact of Dzyaloshinskii-Moriya interaction and large induced magnetization for potential experimental detection.

Reactive capacitance of flat patches of arbitrary shape

This paper investigates the reactive capacitance of flat patches with arbitrary shapes by employing a spectral expansion over a Steklov eigenvalue problem to derive bounds, probabilistic interpretations, and a validated explicit approximation based on surface area and electrostatic capacitance, thereby offering a practical tool for analyzing diffusion-controlled reactions in complex domains.

Evidence of a two-dimensional nitrogen crystalline structure on silver surfaces

This paper reports the experimental synthesis of a two-dimensional nitrogen crystalline structure, termed nitrogene, on silver surfaces via ion-beam-assisted epitaxy, revealing a puckered honeycomb lattice with a predicted band gap of up to 7.5 eV suitable for ultraviolet optoelectronic and high-k dielectric applications.
