摘要：

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. [S1050-2947(97)07911-0].
