Observation of Stückelberg oscillations in accelerated optical lattices
A. Zenesini, D. Ciampini, O. Morsch +1
We report the experimental observation of Stückelberg oscillations of matter waves in optical lattices. Extending previous work on Landau-Zener tunneling of Bose-Einstein condensat…
Expansion of matter waves in static and driven periodic potentials
C. E. Creffield, F. Sols, D. Ciampini +2
We study the non-equilibrium dynamics of cold atoms held in an optical lattice potential. The expansion of an initially confined atom cloud occurs in two phases: an initial quadrat…
Time-resolved measurement of Landau--Zener tunneling in different bases
G. Tayebirad, A. Zenesini, D. Ciampini +5
A comprehensive study of the tunneling dynamics of a Bose--Einstein condensate in a tilted periodic potential is presented. We report numerical and experimental results on time-res…
Optimized loading of an optical dipole trap for the production of Chromium BECs
G. Bismut, B. Pasquiou, D. Ciampini +4
We report on a strategy to maximize the number of chromium atoms transferred from a magneto-optical trap into an optical trap through accumulation in metastable states via strong o…
Ion detection in the photoionization of a Rb Bose-Einstein condensate
M. Viteau, J. Radogostowicz, A. Chotia +7
Two-photon ionization of Rubidium atoms in a magneto-optical trap and a Bose-Einstein condensate (BEC) is experimentally investigated. Using 100 ns laser pulses, we detect single i…
