Pedersen and Miroslav Gajdacz and Nils Winter and Andrew J. Hilliard and Jacob Friis Sherson and Jan J. Arlt}, journal={Physical Review A}, year={2013}, volume={88}, pages={023620} }

Within the combined potential of an optical lattice and a harmonic magnetic trap, it is possible to form matter wave packets by intensity modulation of the lattice. An analysis of the production and motion of these wave packets provides a detailed understanding of the dynamical evolution of the system. The modulation technique also allows for a controllable transfer (de-excitation) of atoms from such wave packets to a state bound by the lattice. Thus, it acts as a beam splitter for matter waves…
