| Resumo | |
We extend Araki's well-known results on the equivalence of the KMS condition and the variational principle for equilibrin states of quantum lattice systems with short-range interactions, to a large class of models possibly containing mean-field interactions (representing an extreme form of long-range interactions). This result is reminiscent of van Heninen's work on equilibrium states for mean-field models. The extension was made possible by our recent outcomes on states mninizing the free energy density of mean-field models on the lattice, as well as on the infinite volume dynamics for such models.
