Universal Slow Growth of Entanglement in Interacting Strongly Disordered Systems
Universal Slow Growth of Entanglement in Interacting Strongly Disordered Systems
Recent numerical work by Bardarson, Pollmann, and Moore revealed a slow, logarithmic in time, growth of the entanglement entropy for initial product states in a putative many-body localized phase. We show that this surprising phenomenon results from the dephasing due to exponentially small interaction-induced corrections to the eigenenergies of different …
