Comparison between optimal control and shortcut to adiabaticity protocols in a linear control system
V. Martikyan, D. Guéry-Odelin, D. Sugny
We analyze the control of the motion of a charged particle by means of an external electric field. The system is constrained to move along a given direction. The goal of the contro…
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…
Direct cooling in an optical lattice by amplitude modulation
M. Arnal, V. Brunaud, G. Chatelain +5
We report on a generic cooling technique for atoms trapped in optical lattices. It consists in modulating the lattice depth with a proper frequency sweeping. This filtering techniq…
Shortcut to stationary regimes: a simple experimental demonstration
S. Faure, S. Ciliberto, E. Trizac +1
We introduce a reverse engineering approach to drive a RC circuit. This technique is implemented experimentally 1) to reach a stationary regime associated to a sinusoidal driving i…
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…
