Fisica Matematica Wulff shape associated to the Ising model. Salvador Miracle-Sole 17-01-2019 - 14:30 Largo San Leonardo Murialdo,1 - Aula F
I will review some aspects of the theory of the Wulff shape in the context of the Ising model. According to the Wulff construction the shape of the equilibrium crystal is determined by the surface tension considered as a function of the interface orientation. We present some (conjectured) approximate solutions and some rigorous results concerning this function, in the case of a lattice gas, and apply them to study the shape of the equilibrium crystal and, in particular, the shape of the facets of this crystal. |
