摘要：

We revisit the nature of the quasi-one-dimensional Ising model on the basis of Wang-Landau simulation. We introduce the density of states in the two-dimensional energy space corresponding to the intra- and interchain directions. We then analyze the interchain coupling dependence of specific heat of the anistropic two-dimensional Ising model in the context of the density of states, and further discuss the size dependence of peak temperature. We also discuss the feature of the phase transition in the three-dimensional case.
