WebbThe first part covers the physics of spin-glass states using results obtained within the framework of the mean field theory of spin glasses. The second part is devoted to the theory of critical phenomena in the presence of weak quenched disorder. This includes a systematic derivation of the traditional renormalization group theory. WebbA spin glassis a diluted magnetic material in which the magnetic moments are randomly interacting, with a huge number of metastable states which prevent reaching …
Webbthe overlap is that small collections of spins become approximately indepen-dent under the Gibbs measure (see [30], Theorem 2.4.10). However, they are not identically distributed unless h= 0. One important objective of the theory of spin glasses is to find ways to compute the marginal distributions of the spins.
