Abstract
Using a characterization of metastability recently introduced by Sewell, taking the ’’lifetime’’ of a state to be determined by the evolution of the polarization density only, we show that the infinite Ising model can support metastable states, describing polarization in opposition to a weak external field, even in the presence of globally acting thermal perturbations.Keywords
