Metastability, nucleation, and noise-enhanced stabilization out of equilibrium
Metastability, nucleation, and noise-enhanced stabilization out of equilibrium
We study metastability and nucleation in a kinetic two-dimensional Ising model that is driven out of equilibrium by a small random perturbation of the usual dynamics at temperature $T$. We show that, at a mesoscopic/cluster level, a nonequilibrium potential describes in a simple way metastable states and their decay. We …
