Kirkpatrick … 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. We stress the role of replica equivalence in obtaining relations which do not depend on the form of replica symmetry breaking. A comparison … WebIt is shown that the ultrametric solution can be obtained from a variational principle and the role of replica equivalence in obtaining relations which do not depend on the form of replica symmetry breaking is stressed.
