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…
Influence of surface roughness on the optical properties of plasmonic nanoparticles
Andreas Truegler, Jean-Claude Tinguely, Joachim R. Krenn +2
For plasmonic nanoparticles, we investigate the influence of surface roughness inherent to top-down fabrication on the optical properties, and find that it has a surprisingly small…
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…
