Fluctuations of the entanglement entropy in strongly disordered systems — •Johannes Oberreuter and Michael Knap — Walter-Schottky-Institut, Technische Universität München, Garching, Deutschland

The fact that disorder localizes the dynamics in one- and two-dimensional systems is a classic result by Anderson. Recently, the question has arisen, if this effect also pertains to quantum many body systems with interactions, which is known as many body localization (MBL). It has been suggested, that the fluctuations of the entanglement entropy could provide a signature of MBL. We examine this quantity in the framework of the strong randomness (real space) renormalization group. We compare numerical simulations and analytical findings in the infinite randomness fixed point.
