    • We note that due to the inhomogeneity of the system, it is hard to define a Mott insulator and its transition to the superfluid. Therefore we suggest that the overdamped regime at zero displacement should be associated with the insulator regime in a more general sense.

    • We note that the coherence loss during the dynamical process is best defined by the value after adiabatically tuning the interaction U to zero. But the results we present here are clear enough to show its qualitative behavior.
