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…
Ultrarobust calibration of an optical lattice depth based on a phase shift
C. Cabrera-Gutiérrez, E. Michon, V. Brunaud +5
We report on a new method to calibrate the depth of an optical lattice. It consists in triggering the intrasite dipole mode of the cloud by a sudden phase shift. The corresponding…
Out-of-equilibrium dynamics of a Bose Einstein condensate in a periodically driven band system
E. Michon, C. Cabrera-Gutierrez, A. Fortun +7
We report on the out-of-equilibrium dynamics of a Bose-Einstein condensate (BEC) placed in an optical lattice whose phase is suddenly modulated. The frequency and the amplitude 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…
Phase space manipulations of many-body wavefunctions
G. Condon, A. Fortun, J. Billy +1
We explore the manipulation in phase space of many-body wavefunctions that exhibit self-similar dynamics, under the application of sudden force and/or in the presence of a constant…
