Abstract: The macroscopic coherent tunneling through the barriers of a periodic potential is used as an atom-optical
filter to separate the center of mass of the condensate and the thermal components of a 87Rb mixed cloud. We
condense in the combined potential of a laser standing wave superimposed on the axis of a cigar-shaped
magnetic trap and induce condensate dipole oscillation in the presence of a static thermal component. The
oscillation is damped due to the interaction with the thermal fraction and we investigate the role played by the
periodic potential in the damping process.
