摘要
We study the nonergodic dynamics of the Ising spin anti-Hebbian model. The mean-field method for Glauber dynamics is reviewed in our context. The resulting one-site problem is described by the memory and noise term, which are expressed by the large-scale convolutions of correlation and response functions. These memory and noise terms are governed by the relation similar to the generalized fluctuation-dissipation relation of nonergodic dynamics. The results of replica method are recovered by studying the onset of very slow dynamics.
