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.

Global thermodynamics for heat-conducting fluids under weak gravity

This paper develops a global thermodynamic framework for liquid-gas coexistence under weak gravity and heat conduction by constructing a variational free-energy function that decomposes into an effective-gravity configurational term and a residual excess-latent-heat contribution, the latter being essential for recovering fundamental thermodynamic relations and reshaping the free-energy landscape.

Run-and-Tumble Escape in Pursuit-Evasion Dynamics of Intelligent Active Particles

This paper investigates the pursuit-evasion dynamics between a deterministic, self-steering pursuer and a stochastic, cognitive evader in two dimensions, revealing that the evader's capture time is significantly influenced by whether it adopts a high-risk backward maneuver or a forward-tumbling strategy with continuous adjustments depending on the pursuer's dominance.
