We study the configurations of minimum energy among those with zero magnetisation in Ising spin glasses. We formulate that problem as a graph partitioning problem and we give an algorithm for it. We determine the concentration of negative interactions such that those configurations give a ground sta

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
