A quantum motor: directed wavepacket motion in an optical lattice
arXiv:1104.3254 · doi:10.1103/PhysRevA.84.043403
Abstract
We propose a method for arbitrary manipulations of a quantum wavepacket in an optical lattice by a suitable modulation of the lattice amplitude. A theoretical model allows to determine the modulation corresponding to a given wavepacket motion, so that arbitrary atomic trajectories can be generated. The method is immediately usable in state of the art experiments.
