Khinchin theorem and anomalous diffusion
Luciano C. Lapas, Rafael Morgado, Mendeli H. Vainstein +2
A recent paper [M. H. Lee, Phys. Rev. Lett. 98, 190601 (2007)] has called attention to the fact that irreversibility is a broader concept than ergodicity, and that therefore the Kh…
Synchronization in the presence of memory
Rafael Morgado, Michal Ciesla, Lech Longa +1
We study the effect of memory on synchronization of identical chaotic systems driven by common external noises. Our examples show that while in general synchronization transition b…
Spatio-temporal conjecture for diffusion
Mendeli H. Vainstein, Rafael Morgado, Fernando A. Oliveira
We present here a conjecture about the equivalence between the noise density of states of a system governed by a generalized Langevin equation and the fluctuation in the energy den…
Superdiffusive Conduction: AC Conductivity with Correlated Noise
Fernando A. Oliveira, Rafael Morgado, Alex Hansen +1
We present evidence of the existence of a superdiffusive regime in systems with correlated disorder for which localization is suppressed. An expression for anomalous electrical con…
Non-exponential relaxation for anomalous diffusion
Mendeli H. Vainstein, Ismael V. L. Costa, Rafael Morgado +1
We study the relaxation process in normal and anomalous diffusion regimes for systems described by a generalized Langevin equation (GLE). We demonstrate the existence of a very gen…
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…
