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.

Fourier dimension of imaginary Gaussian multiplicative chaos

This paper establishes that the Fourier dimension of imaginary Gaussian multiplicative chaos on the unit circle in the subcritical phase is almost surely 1β21-\beta^2, while also proving its failure to belong to a critical Sobolev space and demonstrating that its high-frequency coefficients converge to independent complex Gaussians, effectively behaving as white noise.

Covariant interpretation of proper infall times in Kerr spacetime

This paper investigates how black hole rotation influences proper infall times in Kerr spacetime compared to Schwarzschild spacetime by analyzing equatorial timelike geodesics between surfaces of equal circumferential radius and interpreting the resulting variations through the covariant 1+31+3 formalism, specifically showing that differences in expansion and shear drive distinct focusing behaviors for prograde and retrograde orbits.

When Stochasticity Resolves into Certainty: Hidden Structure of Deterministic Motion

This paper proves that deterministic motion in dissipative systems arises as a strict geometric attractor of contact flow rather than a statistical approximation, demonstrating through the Contact Locking Theorem that exponential probability amplification is precisely counterbalanced by stiffness decay to force macroscopic-microscopic coupling to vanish, a mechanism validated by the damped-driven Duffing oscillator.

The role of asymmetric time delay and its structure in 1D swarmalators

This paper investigates a one-dimensional swarmalator model with asymmetric time delay, revealing that the delay's internal structure fundamentally reshapes the collective phase diagram by systematically expanding the active π\pi state and establishing that the delay's form, rather than just its magnitude, is a decisive factor in emergent swarmalator behavior.

Local Topological Quantum Order and Spectral Gap Stability for the AKLT Models on the Hexagonal and Lieb Lattices

This paper proves that the AKLT models on hexagonal and Lieb lattices satisfy the local topological quantum order condition by establishing the indistinguishability of finite-volume ground states from a unique infinite-volume state via polymer representation analysis, thereby demonstrating the stability of their spectral gaps under small perturbations.
