Numerical results for the Edwards-Anderson spin glass model in two dimensions

A computational method which yields exact thermal averages is reported and applied to L*L Ising systems with random bonds, gaussian distributed (E-A model), in two dimensions. The author obtains Phi =N -1 Sigma (( sigma i sigma j ) T 2 ) J and look for a divergence by examining Psi =-(1/ phi )( delta phi / delta T). Psi obtains its maximum value, Psi max at a temperature of 0.6 approximately, and Psi max increases approximately linearly with L, at least for L
