Webb28 aug. 2010 · Francesco Zamponi These lecture notes focus on the mean field theory of spin glasses, with particular emphasis on the presence of a very large number of metastable states in these systems. This phenomenon, and some of its physical consequences, will be discussed in details for fully-connected models and for models … 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. http://qpt.physics.harvard.edu/c11.pdf milkcake.com
