Space-time phase transitions in driven kinetically constrained lattice models

摘要: Kinetically constrained models (KCMs) have been widely used to study and understand the origin of glassy dynamics. These show an ergodic-nonergodic first-order phase transition between phases distinct dynamical “activity”. We introduce driven variants two popular KCMs, the FA model and (2)-TLG, as for supercooled liquids. By classifying trajectories through their entropy production we prove that driven KCMs display an analogous space-time between dynamical finite vanishing production. discuss how trajectories with rare values can be realized as typical a mapped system modified forces.
