Two different representations of spins -via the conventional fermions, or via the Mattis drone-fermions -are compared considering the planar antiferromagnetic Heisenberg model as an example. Mean-field spin correlation functions calculated for the uniform and flux RVB states show that the drone-ferm

Two dimensional spin-fermion model is studied by using the perturbation method and the spin wave approximation. Non-crossing diagrams are calculated using the dominant pole approximation. As a result, we see that the renormalization parameter z is reduced as z ¢x L -1;4, where L is the linear dimens
The competition between spin glass (SG) and antiferromagnetic order (AF) is analyzed in two-sublattice fermionic Ising models in the presence of a transverse G and a parallel H magnetic fields. The exchange interaction follows a Gaussian probability distribution with mean À4J 0 =N and standard devia
