We examine several definitions of surface tension between oppositely magnetised phases in the two-dimensional Ising model. With nearest-neighbour attractive interactions, we prove that at low temperatures (large β) all the definitions agree with that of Onsager.

Abstract
We examine several definitions of surface tension between oppositely magnetised phases in the two-dimensional Ising model. With nearest-neighbour attractive interactions, we prove that at low temperatures (large β) all the definitions agree with that of Onsager.File allegati a questo prodotto
