A Search for Fluctuation-Dissipation Theorem Violations in Spin-Glasses from Susceptibility Data
arXiv:cond-mat/9905330 · doi:10.1209/epl/i1999-00541-0
Abstract
We propose an indirect way of studying the fluctuation-dissipation relation in spin-glasses that only uses available susceptibility data. It is based on a dynamic extension of the Parisi-Toulouse approximation and a Curie-Weiss treatment of the average magnetic couplings. We present the results of the analysis of several sets of experimental data obtained from various samples.
