The three-dimensional Baxter-Wu Model.

L. N. Jorge, L. S. Ferreira, A. A. Caparica

A classic three-dimensional spin model, based upon the Baxter-Wu scheme, is presented. It is found, by entropic sampling simulations, that the behavior of the energy and magnetization fourth-order cumulants points out to a first order phase transition. A finite-size procedure was performed, confirming that the system scales with the dimensionality d = 3, and yielding a high-resolution estimate of the critical temperature as T c = 11.377577(39).
