Stochastic description of the dynamics of the random-exchange Heisenberg chain
M. H. Vainstein, R. Morgado, F. A. Oliveira +2
We study the diffusion process in a Heisenberg chain with correlated spatial disorder, with a power spectrum in the momentum space behaving as , using a stochastic descript…

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…
