Cumulant ratios and their scaling functions for ising systems in a strip geometry

Abstract

We calculate the fourth-order cumulant ratio (proposed by Binder) for the two-dimensional Ising model in the strip geometry Lxinfinity. The density-matrix renormalization-group method enables us to consider typical open boundary conditions up to L=200. Universal scaling functions of the cumulant ratio are determined for strips with parallel as well as… (More)
