Statistical mechanics explores how the chaotic motion of countless tiny particles gives rise to the predictable laws governing heat, pressure, and phase transitions. This field bridges the gap between the microscopic world of atoms and the macroscopic reality we experience daily, offering deep insights into why materials behave the way they do.

On Gist.Science, we process every new preprint in this category as it appears on arXiv to make these complex findings accessible to everyone. For each paper, we provide both a plain-language explanation for the curious reader and a detailed technical summary for specialists, ensuring that groundbreaking research is never lost behind a wall of jargon.

Below are the latest papers in statistical mechanics, freshly curated and summarized to help you understand the cutting edge of this fascinating discipline.

OPE = QNM

This paper establishes a fundamental connection between the thermal operator product expansion (OPE) and quasinormal modes (QNM) in large-NN CFTs by demonstrating their overlapping convergence in the complex time plane, thereby deriving new analytic results for QNM asymptotics, numerical methods to extract low-overtone QNMs from OPE data, and sum rules that enable a new thermal bootstrap program where these two descriptions mutually constrain each other.

Efficient computation of real-time correlators using Pauli Propagation

This paper presents a hybrid method that overcomes the rapid growth of Pauli strings in classically simulating quantum dynamics by combining accurate short-time Pauli propagation with time-extension techniques based on positivity and characteristic frequencies, thereby enabling the efficient computation of real-time correlators in interacting many-body systems beyond the traditional accessible time window.

A generalized Kirchhoff's law of thermal radiation for Floquet media

This paper derives a generalized Kirchhoff's law for linear time-varying Floquet media, demonstrating that thermal emissivity at a specific frequency equals a weighted sum of harmonic-resolved absorptivities in the adjoint system, thereby enabling near-maximal violations of the conventional law where strong emission occurs with negligible same-frequency absorption.

Logarithmic Aging Diffusion from a Multiplicative Event Clock: Rare Event Statistics, Ultraslow Transport, and Ensemble-Time Inequivalence

This paper introduces a multiplicative event clock model that generates logarithmic aging and ultraslow transport through independent logarithmic time ratios, revealing a fundamental inequivalence between ensemble and time-averaged statistics while providing a comprehensive framework to distinguish this specific mechanism from other models that merely exhibit similar logarithmic relaxation curves.

Critical Ripples and Dirac Fermions in Crystalline Membranes

This paper develops a low-energy field theory for crystalline membranes with Dirac fermions, demonstrating that while the flat phase remains stable against coupling due to a dynamical mismatch, the system can undergo a hybrid electronic-structural phase transition governed by the chiral-XY Gross-Neveu-Yukawa universality class when symmetry permits a mass-type Dirac bilinear to couple with ripple modes.
