A non-classical van der Waals loop: Collective variables method
arXiv:1210.3737 · doi:10.5488/CMP.16.14001
Abstract
The equation of state is investigated for an Ising-like model in the framework of collective variables method. The peculiar feature of the theory is that a non-classical van der Waals loop is extracted. The results are compared with the ones of a trigonometric parametric model in terms of normalized magnetization, \tilde{M}, and field, \tilde{H}.
