Phys. Rev. Lett. 88, 093003 (2002) [4 pages]Feedback Control of Atomic Motion in an Optical LatticeReceived 28 September 2001; published 15 February 2002 We demonstrate a real-time feedback scheme to manipulate wave-packet oscillations of atoms in an optical lattice. The average position of the atoms in the lattice wells is measured continuously and nondestructively. A feedback loop processes the position signal and translates the lattice potential. Depending on the feedback loop characteristics, we find amplification, damping, or an entire alteration of the wave-packet oscillations. Our results are well supported by simulations. © 2002 The American Physical Society URL:
