@article{2003-mandel-bloch-phys-rev-lett-v91-p010407, Abstract = {We demonstrate the controlled coherent transport and splitting of atomic wave packets in spin-dependent optical lattice potentials. Such experiments open intriguing possibilities for quantum state engineering of many body states. After first preparing localized atomic wave functions in an optical lattice through a Mott insulating phase, we place each atom in a superposition of two internal spin states. Then state selective optical potentials are used to split the wave function of a single atom and transport the corresponding wave packets in two opposite directions. Coherence between the wave packets of an atom delocalized over up to seven lattice sites is demonstrated.}, Author = {Mandel, O. AND Greiner, M. AND Widera, A. AND Rom, T. AND Hänsch, T. W.
