DROPLET DYNAMICS OF ISING FERROMAGNETS AT THE CRITICAL POINT
Cluster numbers in the 2D Ising model at and above the Curie temperature Tc are observed in computer simulations. While at 1.1 Tc we find all cluster numbers to relax towards zero exponentially, with the same decay time for long times, right at the Curie temperature a different (scaling) behavior sets in. These results are in qualitative agreement with the Becker-Döring equation for the cluster numbers.
