On the Replica Approach to Spin Glass - CORE

WebThe Edwards-Anderson model of spin glasses and its treatment within the replica method and mean-field theory are outlined, and concepts such as "frustration," "broken replica symmetry," "broken ergodicity," etc., are discussed. The dynamic approach to describing the spin glass transition is emphasized. WebThe authors argue that in order to describe dilute dipolar or RKKY spin-glasses, a broad distribution of couplings (i.e decaying as a power law) is more appropriate than the traditional Gaussian distribution. They present a mean-field 'replica symmetric' theory for this problem. They find that the spin-glass transition is of a different nature than the one … Web9 de jan. de 1998 · In this paper we review the predictions of the replica approach on the probability distribution of the overlaps among replicas and on the sample to sample fluctuations of this probability.
