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 extends a perturbative framework to calculate the partial entropy production of active particles with hidden self-propulsion in generic confining potentials, successfully reproducing exact results for active Ornstein-Uhlenbeck particles and deriving new rates for run-and-tumble particles in harmonic traps.
This paper establishes a combinatorial framework for the finite-time transition probabilities of the Totally Asymmetric Simple Exclusion Process with open boundaries by demonstrating that these probabilities can be expressed as signed sums of exponential generating functions associated with standard Young tableaux of non-classical shapes and generalized tableau-like objects.
This paper introduces and validates a Monte Carlo-based inference protocol for generalised spin models (Ising, Blume-Capel, and Blume-Emery-Griffiths) to analyze ordinal questionnaire data, demonstrating that the Blume-Emery-Griffiths model outperforms traditional Gaussian approaches in capturing complex features like multi-modality and outliers, though all models struggle with heavy-tailed distributions.
This paper proposes gate-parameter Lee-Yang zeros of Loschmidt amplitudes as a universal, non-integrability-dependent diagnostic for dynamical phase transitions in finite quantum circuits, demonstrating how these zeros condense onto limiting curves governed by Floquet eigenvalue competition and state overlaps to signal abrupt reorganizations indicative of phase changes.
This paper extends the "Brownian bees" model to cooperative reproduction on a lattice, using a hydrodynamic free-boundary formalism to characterize steady states, stability, and the transition between diffusive spreading and finite-time collapse as the cooperation order varies.
This paper utilizes an Enskog-Vlasov kinetic model to demonstrate that isochoric cooling allows liquids to reach lower supercooled temperatures than isobaric cooling, while predicting that surface tension diverges at the spinodal temperature due to the emergence of an infinite oscillatory region as the liquid approaches instability.
This study employs a mean-field approach to analyze the thermodynamic properties and phase transitions of the quantum spin-5/2 Blume-Capel model under random transverse-crystalline field anisotropy, revealing that while the system typically exhibits second-order transitions, specific positive anisotropy values induce first-order transitions between different spin-ordered states, with critical temperatures being significantly modulated by the sign and magnitude of the anisotropy parameters.
This paper demonstrates that long-range entanglement in finite-temperature topological orders can be characterized by an emergent symmetry-protected topological order localized on the entangling surface, providing a framework to diagnose universal entanglement patterns and understand their stability against thermal fluctuations.
This paper analytically demonstrates that boundary decoherence can induce a disentangling transition in topological orders by establishing a connection between the negativity spectrum of decohered mixed states and emergent symmetry-protected topological orders, thereby enabling the exact calculation of topological entanglement negativity without relying on the replica trick.
This paper investigates the spontaneous symmetry breaking of non-onsite symmetries in one and two spatial dimensions, revealing novel phases characterized by the coexistence of distinct symmetry-protected topological orders, long-range entanglement, and topological quantum criticality.
