Elementary solution of Classical Spin-Glass models

An elementary solution to a general class of classical spin-glass models is presented. This class comprises all mean-field models where bond-randomness is given in terms ofsite-randomness with finitely many random variables per site and includes both separable and non-separable interactions. The main idea is to single out specific sublattice magnetizations which correspond to the probability distribution and to determine their asymptotics by means of a simple large-deviations argument. The ensuing stability and bifurcation analysis is given in detail.
