Dynamic critical behavior in Ising spin glasses

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 z(c), the nonequilibrium autocorrelation decay exponent lambda(c)/z(c), and the critical fluctuation-dissipation ratio X-infinity all vary strongly and systematically with the form of the interaction distribution.
