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.

Non-equilibrium thermodynamics of collapse models in the strongly non-Gaussian regime

This paper rigorously establishes the thermodynamic consistency of the dissipative Diósi-Penrose collapse model in the strongly non-Gaussian regime by employing a novel exact pseudo-spectral simulation approach to demonstrate that the system settles into a non-equilibrium steady state with asymptotic non-Gaussianity scaling as the cube of the dissipation parameter, thereby resolving the unphysical heating issue while confirming the necessity of exact numerical methods for capturing critical distribution tails.

Early psychosis shows deviations in scaling behaviour within a critical regime

This study reveals that early psychosis is characterized not by a loss of critical-like brain dynamics, but by a systematic reorganization of scaling exponents within a preserved scale-invariant regime, as demonstrated by combining phenomenological renormalization group, power spectral density, and detrended fluctuation analysis on resting-state fMRI data.
