Central limit theorem for fluctuations in the high temperature region of the Sherrington-Kirkpatrick spin glass model
arXiv:cond-mat/0201092 · doi:10.1063/1.1515109
Abstract
In a region above the Almeida-Thouless line, where we are able to control the thermodynamic limit of the Sherrington-Kirkpatrick model and to prove replica symmetry, we show that the fluctuations of the overlaps and of the free energy are Gaussian, on the scale N^{-1/2}, for N large. The method we employ is based on the idea, we recently developed, of introducing quadratic coupling between two replicas. The proof makes use of the cavity equations and of concentration of measure inequalities for the free energy.
