Bethe-Peierls Approximation for the 2D Random Ising Model
arXiv:cond-mat/9511047 · doi:10.1088/0305-4470/29/7/011
Abstract
The partition function of the 2d Ising model with random nearest neighbor coupling is expressed in the dual lattice made of square plaquettes. The dual model is solved in the the mean field and in different types of Bethe-Peierls approximations, using the replica method.
