Universal dependence of the fluctuation–dissipation ratio on the transition rates in trap models
Universal dependence of the fluctuation–dissipation ratio on the transition rates in trap models
We investigate violations of the fluctuation-dissipation theorem in two classes of trap models by studying the influence of the perturbing field on the transition rates. We show that for perturbed rates depending upon the value of the observable at the arrival trap, a limiting value of the fluctuation-dissipation ratio does …
