Resonant excitations of a Bose Einstein condensate in an optical lattice
C. Cabrera-Gutiérrez, E. Michon, M. Arnal +4
We investigate experimentally a Bose Einstein condensate placed in a 1D optical lattice whose phase or amplitude is modulated in a frequency range resonant with the first bands of…

Direct tunneling delay time measurement in an optical lattice
A. Fortun, C. Cabrera-Gutiérrez, G. Condon +3
We report on the measurement of the time required for a wave packet to tunnel through the potential barriers of an optical lattice. The experiment is carried out by loading adiabat…
