Phase transitions in the neighbourhood of mean field theory

We study systems consisting of interacting spin particles which can have a positive or negative spin. We consider an Ising model and a type of Widom-Rowlinson (WR) model. The interactions between spin particles are regulated by Kac potentials which carry a parameter ɣ. It is known that in the Kac li...
