For power-law forms $D(x) \\simeq|x|^{\\alpha}$, this process yield anomalous diffusion of the form $\\ < x^2(t)\\ > \\simeq t^{2/(2-\\alpha)}$. Interestingly, in both the sub- and superdiffusive regimes we observe weak ergodicity breaking: the scaling of the time averaged mean squared displacement $\\{\\delta^2}$ remains \\emph{linear} and thus differs from the corresponding ensemble average $\\ <x^2(t)\\ >$.
