Vibrational state inversion of a Bose-Einstein condensate: optimal control and state tomography
Robert Bücker, Tarik Berrada, Sandrine van Frank +6
We present theoretical and experimental results on high-fidelity transfer of a trapped Bose-Einstein condensate into its first vibrationally excited eigenstate. The excitation is d…
Momentum distribution of 1D Bose gases at the quasi-condensation crossover: theoretical and experimental investigation
Thibaut Jacqmin, Bess Fang, Tarik Berrada +2
We investigate the momentum distribution of weakly interacting 1D Bose gases at thermal equilibrium both experimentally and theoretically. Momentum distribution of single 1D Bose g…
Dynamics of parametric matter wave amplification
Robert Bücker, Ulrich Hohenester, Tarik Berrada +7
We develop a model for parametric amplification, based on a density matrix approach, which naturally accounts for the peculiarities arising for matter waves: significant depletion…
