Abstract: The presence of disorder in a non-interacting system can localize all the energy eigenstates, a phenomena dubbed Anderson localization. Many-body localization is an extension of this phenomena to include interactions. Effects of interactions show up in the logarithmic growth of entanglement after a global quench. We perform a systematic study of the evolution and saturation of entanglement and show that it can be used to detect the localization transition. We consider the bipartite fluctuation which also captures the transition and is promising as an experimental probe. We compare these results to that of a non-interacting system and note important differences between the two.
