  Matter wave revivals depend on a delicate interplay of constructive many-body
quantum interferences in the developing dynamics of an ultracold bosonic system
in an optical lattice. It is shown that the interplay between weak intersite
tunneling and strong onsite interactions can lead to the quantum dynamics of a
density wave displaying several features not found in the mean-field limit:
occupancy oscillations, resurgent revivals, and a (anti-) synchronization of
revival peaks and occupancy oscillation peaks. This implies cooperative
interference effects that alternate between constructive and destructive
features leading to the peak revival behaviors. These many-body quantum
interference phenomena create striking features in various observables, which
are accessible in experimental measurements.
