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 demonstrates that sufficiently long-ranged quenched disorder can induce long-range order and novel phase transitions in nonreciprocal active systems across two and three dimensions, with critical exponents that vary continuously based on the disorder's transversality.
This paper presents a generalized one-dimensional random sequential adsorption model with charge-dependent deposition that interpolates between uniform and localized regimes, deriving exact statistical recursions to prove the self-averaging nature of jammed density and demonstrating that charge selectivity significantly enhances coverage while reducing fluctuations.
This paper demonstrates that the exact renormalization group flow of density matrices in quantum field theory is governed by a Lindblad master equation, where dissipative terms drive the correct coupling flow and ensure that state distinguishability serves as a renormalization group monotone via the data processing inequality.
This paper proposes and validates an operational method to determine the unobservable bare shear viscosity in two-dimensional dense fluids by measuring viscosity near solid boundaries where hydrodynamic fluctuations are suppressed, thereby demonstrating that fluctuating hydrodynamics accurately describes fluid behavior down to atomic scales.
This paper investigates an assembly of scalar fields with quenched random couplings, revealing that for large , the system exhibits Gaussian universality classes with critical exponents determined by the spectral edge of the coupling matrix, where a Wigner matrix leads to a divergent correlation length with finite susceptibility and an upper critical dimension of unity, while a spherical variant displays a heat capacity jump and generic scale invariance in the glass phase.
This paper demonstrates that fluctuation-response relations in a rotating stochastic Landau model emerge from an inherent symmetry of the coarse-grained Martin-Siggia-Rose path integral, which links entropy production to time-reversed dynamics and yields Ward identities that align with high-temperature fluctuation-dissipation relations only upon imposing the Einstein relation.
By combining N-body simulations with non-extensive statistical mechanics and superstatistics theory, this paper demonstrates that a concise two-parameter Tsallis distribution accurately models the non-Gaussian peculiar velocities of dark matter halos across redshifts 0–2, offering a promising tool for probing cosmological parameters.
This paper proposes a parameter-free integral equation for the rate function governing the emptiness formation probability in the ground state of the repulsive Lieb-Liniger Bose gas, deriving it from a dual-field Fredholm-determinant representation and validating it against known limits and extensive numerical hydrodynamic simulations.
This paper bridges geometric optimality and Mpemba-effect-based acceleration by demonstrating that entanglement-assisted operations can redistribute local coherences to enable individual qubits to follow geodesic paths toward the ground state, even when the collective system evolution is suboptimal.
This paper demonstrates that quenched activity induces identical hydrodynamic behavior in nonreciprocal random bond XY models and active surfaces, leading to nonuniversal, continuously varying scaling exponents for phase and positional order that depend on the disorder's transversality.
