Violation of the fluctuation-dissipation theorem for fast superdiffusion
Ismael V. L. Costa, Rafael Morgado, Marcos V. B. T. Lima +1
We study anomalous diffusion for one-dimensional systems described by a generalized Langevin equation. We show that superdiffusion can be classified in normal superdiffusion and fa…
