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 establishes the first rigorous end-to-end theory for tensor network belief propagation on strongly injective projected entangled pair states, proving that the algorithm converges efficiently and exhibits "algorithmic locality," which allows local perturbations to be handled via local recomputation and enables accurate approximation of physical quantities in polynomial time.
This paper demonstrates that a driven lattice gas with a partially penetrable obstacle exhibits a nonequilibrium transition to a two-domain steady state characterized by local invariants ("obstacle edges") that provide a protection effect against external noise and spatially localize fluctuations, with distinct relaxation mechanisms governed by shock wave generation in sub- and overcritical regimes.
This paper presents a data-driven framework combining short-time thermodynamic uncertainty relations with deep learning to accurately reconstruct dissipative force fields and localize fluctuating entropy production in space and time along non-equilibrium trajectories from experimental data.
This study investigates the finite-temperature phase diagram of two-dimensional soft-core bosons using self-consistent Hartree-Fock and quantum Monte Carlo methods, identifying a broad supersolid phase and a potential intermediate hexatic phase while validating mean-field theory as an effective tool for analyzing these transitions.
This paper introduces a framework for defining phases of data distributions to demonstrate that diffusion models can utilize efficient local denoisers for most of the generation process, reserving computationally expensive global networks only for the narrow time interval of a critical phase transition.
This paper derives universal fluctuation relations and a Thermodynamic Uncertainty Relation for non-Abelian quantum transport, demonstrating how the non-commutativity of conserved charges can lead to apparent second law violations, enhanced current precision, and current inversion without requiring efficacy parameters.
This paper investigates the entanglement asymmetry of free fermions on a honeycomb lattice with sublattice energy imbalance, revealing that the asymmetry exhibits nonanalytic dependence on the imbalance due to Dirac points and persists after a quench to the symmetric point because of a flat energy dispersion in a specific direction.
This paper establishes an exact identity linking the total entropy production rate in overdamped Langevin dynamics to mutual information and a mean flow term, enabling a forward-only characterization of irreversibility and a canonical nonnegative decomposition of subsystem entropy production into self and interaction components.
This paper develops a kinetic-theory framework based on the Boltzmann equation and Grad's moment expansion to derive and validate, via DSMC simulations, the steady rheology and transport coefficients of dilute weakly charged granular gases under uniform shear flow, demonstrating excellent agreement and near-Maxwellian velocity distributions even under strong shear.
This paper analyzes the quantum correlations and critical behaviors of two stacked quantum Ising subsystems coupled by a -preserving interaction, revealing that when both subsystems are critical, the system maps to the quantum Ashkin-Teller model and exhibits a continuous variation of critical exponents in one dimension and an emergent O(2) symmetry in two dimensions.
