E, Melville, v. 73, e036702, 2006.e- 1550-2376http://repositorio.bc.ufg.br/handle/ri/15212We carry out a study of the two-dimensional Blume-Capel model using the Wang-Landau Monte Carlo method which estimates the density of states g E directly. This work validates the applicability of this method to multiparametric systems, since only one computer run is needed for all range of macroscopic parameters temperature, anisotropy, etc. . The location of the tricritical point is determined as kBTt /J=0.609 3 , Dt /J =1.966 2 and is in excellent agreement with previous estimates. The free energy and the entropy, which are not directly accessible by conventional Monte Carlo simulations, are obtained simply using g E .engAcesso AbertoArtigo10.1103/PhysRevE.73.036702
