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. In this paper we review the predictions of the replica approach on the probability distribution of the overlaps among replicas and on the … Web19 de mai. de 2024 · Finally, in the case of Ising spins, Panchenko’s recent rigorous calculation (Panchenko in Ann Probab 46(2):865–896, 2024) of the free energy for a system of “two real replica” enables us to prove a quenched LDP for the overlap distribution, which gives us a wider criterion for slow mixing directly related to the Franz–Parisi–Virasoro …

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.
