Dynamic critical behaviour in Ising spin glasses

Disordered Systems and Neural Networks 2009-11-11 v3

Abstract

The critical dynamics of Ising spin glasses with Bimodal, Gaussian, and Laplacian interaction distributions are studied numerically in dimensions 3 and 4. The data demonstrate that in both dimensions the critical dynamic exponent zcz_{\rm c}, the non-equilibrium autocorrelation decay exponent λc/zc\lambda_c/z_{\rm c}, and the critical fluctuation-dissipation ratio XX_{\infty} all vary strongly and systematically with the form of the interaction distribution.
