Acesso em: 29 nov. 2012.10953787http://www.repositorio.ufop.br/handle/123456789/1887We study the early time behavior of the Baxter-Wu model, an Ising model with three-spin interactions on a triangular lattice. Our estimates for the dynamic exponent z are compatible with results recently obtained for two models which belong to the same universality class of the Baxter-Wu model: the two-dimensional four-state Potts model and the Ising model with three-spin interactions in one direction. However, our estimates for the dynamic exponent theta of the Baxter-Wu model are completely different from the values obtained for those models. This discrepancy could be related to the absence of a marginal operator in the Baxter-Wu model.en-USArtigo publicado em periodicoO periódico Physical Review E permite o depósito da versão PDF do editor em repositório institucional.
