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.

Diagrammatic bosonization, aspects of criticality, and the Hohenberg-Mermin-Wagner theorem in parquet approaches

This paper establishes a diagrammatic mapping between fermionic polarizations in the single-boson exchange formalism and bosonic self-energies, thereby validating the identification of screened interactions as bosonic propagators, recovering trace log theory under specific approximations, and clarifying how parquet approaches enforce the Hohenberg-Mermin-Wagner theorem.

T-square electric resistivity and its thermal counterpart in RuO2_2

This study establishes RuO2_2 as a weakly correlated Fermi liquid by revealing a previously undetected quadratic temperature dependence in its electric resistivity that follows Kadowaki-Woods scaling, while thermal transport measurements show a deviation from the Wiedemann-Franz law at finite temperatures, providing critical data for first-principles theories of electron-electron scattering in metallic oxides.

Exact strong zero modes in quantum circuits and spin chains with non-diagonal boundary conditions

This paper constructs exact strong zero mode operators in integrable quantum circuits and the spin-1/2 XXZ chain with non-diagonal open boundary conditions that break bulk U(1) symmetry, demonstrating their role in inducing infinite boundary coherence times while showing they become spatially non-local and dynamically insignificant when mapped to the asymmetric simple exclusion process.
