Abstract

By a recursive method numerically exact free energies are calculated for square L×L Ising lattices, with 6<~L<~18, for several kinds of frozen-in bond disorder: (i) bonds ±J with various concentrations of negative bonds; (ii) bonds distributed according to a Gaussian distribution. Ground states of these systems are identified, the response to "ordering fields" is studied, and the correlation ...
