Size dependence of the lifetime of metastable states in the kinetic one-spin-flip Ising model

Abstract

For large square Ising systems, the lifetime of metastable states is size independent. For small systems, however, the reciprocal relaxation time is proportional to the probability for the occurence of a cluster covering the half system. In an intermediate range, this inverse relaxation time grows with the number of spins. © 1977.
