摘要：

We study the evolution of the von Neumann entropy in a fermionic interacting system at infinite temperature finding two different regimes. A metallic one at low values of the disorder and an insulating regime for strong disorder. In the insulating regime, the entropy evolves logarithmically with time, which is consistent with a Many-Body localized phase, and the slope characterizing this behavior is proportional to the localization length. Finally we have estimated the position of the Many-Body localization transition extrapolating the inverse of this slope in the insulating regime.
