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.
This paper presents a data-driven framework that integrates short-time thermodynamic uncertainty relations with deep learning to accurately reconstruct dissipative force fields and spatiotemporally localize entropy production along non-equilibrium trajectories in complex systems.
This paper demonstrates that coupling a one-dimensional Ising chain to a cavity photon mode induces an exactly solvable finite-temperature superradiant phase transition, a phenomenon impossible in the isolated classical 1D system due to the emergence of long-range fully connected interactions mediated by photons.
This paper extends the deconfined quantum criticality paradigm to systems with internal supersymmetry by proposing a supersymmetric deconfined quantum critical point (sDQCP) between an $OSp(1|2)$-breaking phase and a lattice rotation-breaking phase, which is described via a non-linear sigma model on a supersphere and a gauge theory, and shown to continuously connect to the conventional DQCP when supersymmetry is explicitly broken.
This paper demonstrates that for a classical Brownian oscillator, the generalized Langevin equation with linear dissipation satisfies the Jarzynski equality at finite times only if the thermal noise is Gaussian (beyond seventh-order perturbation), rendering non-Gaussian variants superfluous for evaluating properties beyond linear or quadratic noise dependence.
This paper investigates the elastocaloric response of frustrated Ising and Heisenberg magnets on anisotropic triangular and kagome lattices under uniaxial strain, demonstrating that the elastic Grüneisen ratio serves as a universal probe for extensive ground-state entropy in classical spin liquids and reveals distinct low-temperature signatures of quantum phase transitions in spin- systems.
This paper extends the Tolman-Ehrenfest effect to coupled thermodynamic channels by deriving a unique invariant involving the Ruppeiner connection holonomy, which geometrically resolves long-standing puzzles in granular matter physics and predicts a testable relationship for shear bands.
This study utilizes large-scale Monte Carlo simulations to characterize the short-time critical dynamics of the classical cubic dimer model, determining its critical temperature and static exponents while revealing an anomalous negative initial slip exponent () driven by emergent SO(5) symmetry and local U(1) gauge constraints, thereby providing the first comprehensive nonequilibrium analysis of this system beyond the Landau-Ginzburg-Wilson paradigm.
This paper demonstrates that the late-time dynamics of a minimal three-component mass-conserving reaction-diffusion system reduce to Active Model B, a scalar active field theory where a density-dependent negative interfacial coefficient drives finite-wavelength instabilities that stabilize microphase-separated patterns, distinguishing it from the unbounded coarsening typical of two-component systems.
This paper derives the large- scaling of Tan's contact for harmonically trapped Tonks--Girardeau bosons at finite temperature by identifying a new subleading coefficient that quantifies the canonical-versus-grand-canonical ensemble difference, providing explicit universal representations and accurate Padé approximants that interpolate between low- and high-temperature regimes.
This paper investigates a one-dimensional alternating particle system with elastic collisions, demonstrating that while equidistant initial positions with a mass ratio of 2 exhibit hydrodynamic shock front behavior similar to random initial conditions, specific mass ratios induce a unique "staggering domino-like" regime where only a single triplet moves at any time, resulting in ballistic shock front propagation.
