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…
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…
Excitation spectra of fragmented condensates by linear response: General theory and application to a condensate in a double-well potential
Julian Grond, Alexej I. Streltsov, Ofir E. Alon +1
Linear response of simple (i.e., condensed) Bose-Einstein condensates is known to lead to the Bogoliubov- de Gennes equations. Here, we derive linear response for fragmented Bose-E…
