Ordering dynamics in the presence of multiple phases

Abstract

The dynamics of the 2D Potts ferromagnet when quenched below the transition temperature is investigated in the case of discontinuous phase transition, which is interesting for understandingthe non equilibrium dynamics of systems with many competing equivalent low temperature phases, that appears to be not much explored. After briefly reviewing some recent findings, we focus on the numerical study of quenches just below the transition temperature on square lattices. We show that, up to a certain time, metastable states can be observed for which energy stays constant above the equilibrium energy and the self-correlation function displays a fast decay.
