Quantum state control of a Bose-Einstein condensate in an optical lattice
N. Dupont, G. Chatelain, L. Gabardos +5
We report on the efficient design of quantum optimal control protocols to manipulate the motional states of an atomic Bose-Einstein condensate (BEC) in a one-dimensional optical la…
Observation and control of quantized scattering halos
G. Chatelain, N. Dupont, M. Arnal +5
We investigate the production of s-wave scattering halos from collisions between the momentum components of a Bose-Einstein condensate released from an optical lattice. The lattice…
Chaos-assisted tunneling resonances in a synthetic Floquet superlattice
M. Arnal, G. Chatelain, M. Martinez +7
The field of quantum simulation, which aims at using a tunable quantum system to simulate another, has been developing fast in the past years as an alternative to the all-purpose q…
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…
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…
