Ergodicity Breaking and Scaling Relations for Finite-Time First-Order Phase Transition

arXiv:2401.15592 · doi:10.1103/PhysRevLett.134.177101

Abstract

Hysteresis and metastable states are typical features associated with ergodicity breaking in the first-order phase transition. We explore the scaling relations of nonequilibrium thermodynamics in finite-time first-order phase transitions. Using the Curie-Weiss model as an example, for large systems we find the excess work scales as when the magnetic field is quenched at a finite rate across the phase transition. We further reveal a crossover in the scaling of the excess work from to when downsizing the system. Our study elucidates the interplay between the finite-time dynamics and the finite-size effect, which leads to different scaling behaviors of the excess work with or without ergodicity breaking.
