Trap modulation spectroscopy of the Mott-insulator transition in optical lattices
H. Lignier, A. Zenesini, D. Ciampini +5
We introduce a new technique to probe the properties of an interacting cold atomic gas that can be viewed as a dynamical compressibility measurement. We apply this technique to the…
Exploring dynamic localization with a Bose-Einstein condensate
Andre Eckardt, Martin Holthaus, Hans Lignier +4
We report on the experimental observation of dynamic localization of a Bose-Einstein condensate in a shaken optical lattice, both for sinusoidal and square-wave forcing. The formul…
Coherent control of dressed matter waves
Alessandro Zenesini, Hans Lignier, Donatella Ciampini +2
By moving the pivot of a pendulum rapidly up and down one can create a stable position with the pendulum's bob above the pivot rather than below it. This surprising and counterintu…
