Phys. Rev. A 56, 4331–4334 (1997)Revivals, damping, and coherence times of atomic wave packets in optical latticesReceived 2 June 1997; published in the issue dated November 1997 We present a study of the time evolution of wave packets excited in optical lattices. Our model shows that, after a sudden change of the potential well depth, a breathing oscillation is created, in agreement with recently performed experiments. We predict that this motional wave packet should subsequently collapse and revive, with a rich intermediate structure comprised of fractional revivals. Moreover, we estimate the rate of damping of the oscillations due to the interaction of the atoms with light and other experimental constraints. © 1997 The American Physical Society URL:
