Metastability and nucleation in Ising models with Swendsen-Wang dynamics

Abstract

The cluster numbers of stable phase droplets in the metastable state and nucleation rates for the three-dimensional Ising model with Swendsen-Wang dynamics are measured for T = 0.59 Tc and compared with previous Metropolis results. Both dynamics appear to give the same metastable properties. When the external field is small the results agree with classical nucleation theory. No evidence is found for the existence of a spinodal line.
