Spinodal-like scaling behavior after a temperature quench across the first-order phase transition in three-dimensional -state Potts models
Andrea Pelissetto, Davide Rossini, Ettore Vicari
We study the out-of-equilibrium spinodal-like behavior of three-dimensional (3D) -state Potts models (for ), observed when the temperature is quenched across the first-o…
