Beyond effective Hamiltonians: micromotion of Bose Einstein condensates in periodically driven optical lattices
M. Arnal, G. Chatelain, C. Cabrera-Gutiérrez +5
We investigate a Bose Einstein condensate held in a 1D optical lattice whose phase undergoes a fast oscillation using a statistical analysis. The averaged potential experienced by…

Fast phase-modulated optical lattice for wave packet engineering
C. Cabrera-Gutiérrez, A. Fortun, E. Michon +4
We investigate experimentally a Bose Einstein condensate placed in a 1D optical lattice whose phase is modulated at a frequency large compared to all characteristic frequencies. As…

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…
