We find that the claimed ultra-slow entanglement growth results from this fragmentation, and show (including with matrix product state simulations) that is more naturally explained by a single-log at short times with a slow power-law relaxation to a finite-size saturation value at late times: (5/7)

What does this all mean? Our results suggest apparent signatures of a many-body localised (MBL) phase can be accounted for by a single phase deriving from the observed fragmentation in the infinite-coupling limit, rather than the mechanisms of conventional disorder-driven MBL (6/7)
