We consider a particular four state spin system composed of two Ising spins (sxr rX) with independent hopping parameters KI, Kz, coupled by a bilinear Yukawa term, ysxax. The Yukawa term is solely responsible for breaking the global 22 x ZZ symmetry down to Z2. This model is intended as an illustrat
