【 摘 要 】

We use the statistical properties of the entanglement spectrum of an interacting disordered system, in order to track the localized to extended transition as function of interaction strength and excitation energy expected from the many-body localization transition. We show that such a transition is indeed observed, although an interesting saturation behavior in the intermediate excitation energy is seen.
