Abstract

Abstract Decay of the metastable state of the one-dimensional Ising model with an x - α potential is investigated using instanton (critical droplet) techniques. Calculations indicating that the analytic structure of the free energy is modified by droplet-droplet interactions for 1 < α ≲ 1.2 are presented.
