We perform a duality transformation that allows one to express the partition function of the d-dimensional Ising model with random nearest neighbor coupling in terms of spin variables defined on the square plaquettes of the lattice. The dual model is solved in the mean-field approximation.

Abstract
We perform a duality transformation that allows one to express the partition function of the d-dimensional Ising model with random nearest neighbor coupling in terms of spin variables defined on the square plaquettes of the lattice. The dual model is solved in the mean-field approximation.File in questo prodotto:
