Aging rate of spin glasses from simulations matches experiments

Experiments on spin glasses can now make precise measurements of the exponent zðTÞ governing the growth of glassy domains, while our computational capabilities allow us to make quantitative predictions for experimental scales. However, experimental and numerical values for zðTÞ have differed. We use...

Sumario:Experiments on spin glasses can now make precise measurements of the exponent zðTÞ governing the growth of glassy domains, while our computational capabilities allow us to make quantitative predictions for experimental scales. However, experimental and numerical values for zðTÞ have differed. We use new simulations on the Janus II computer to resolve this discrepancy, finding a time-dependent zðT; twÞ, which leads to the experimental value through mild extrapolations. Furthermore, theoretical insight is gained by studying a crossover between the T ¼ Tc and T ¼ 0 fixed points.
