Abstract
Using Bragg scattering we study classical squeezing and wave packet os cillations of the atomic center-of-mass motion of cesium atoms trapped in 1D and 3D optical lattices. A sudden increase of the potential dep th leads to wave packets substantially more localized than in steady s tate, and subsequent breathing-mode oscillations with a decay rate tha t under some conditions is remarkably slow. We also study the response of the atoms to parametric driving of the center-of-mass motion. Our results are in agreement with Monte Carlo simulations.
