The critical temperature of the two-dimensional ± J Ising spin glass
We have studied the two-dimensional ± J Ising model on the square lattice with a view to determine whether a spin glass can exist at small finite temperatures. By mapping the Ising model onto an ensemble of non-interacting lattice fermions, we have shown that the critical temperature for the spin gl...
