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…
Resonant tunneling of Bose-Einstein condensates in optical lattices
Alessandro Zenesini, Carlo Sias, Hans Lignier +7
In this article, we present theoretical as well as experimental results on resonantly enhanced tunneling of Bose-Einstein condensates in optical lattices both in the linear case an…
Dynamical control of matter-wave tunneling in periodic potentials
H. Lignier, C. Sias, D. Ciampini +4
We report on measurements of dynamical suppression of inter-well tunneling of a Bose-Einstein condensate (BEC) in a strongly driven optical lattice. The strong driving is a sinusoi…
Resonantly enhanced tunneling of Bose-Einstein condensates in periodic potentials
C. Sias, A. Zenesini, H. Lignier +4
We report on measurements of resonantly enhanced tunneling of Bose-Einstein condensates loaded into an optical lattice. By controlling the initial conditions of our system we were…
