    We propose an inverse method to accelerate without final excitation the adiabatic transport of a Bose-Einstein condensate. The method is based on a partial extension of the Lewis-Riesenfeld invariants and provides transport ...
  • Joellenbeck, S.; Mahnke, J.; Randoll, R.; Ertmer, Wolfgang; Arlt, Jan J.; Klempt, Carsten (College Park : American Physical Society, 2011)
    Magneto-optical traps on atom chips are usually restricted to small atomic samples due to a limited capture volume caused primarily by distorted field configurations. Here we present a magneto-optical trap based on a ...

  • Dahlke, Veit (Hannover : Institutionelles Repositorium der Leibniz Universität Hannover, 2020)
    In this thesis I present the results of photoassociation measurements in ensembles of atomic calcium over an intensity range of below 1 W/cm2 up to 600 W/cm2. The temperature of the atoms was reduced to 1 μK by laser and ...
  • Voges, Kai Konrad (Hannover : Institutionelles Repositorium der Leibniz Universität Hannover, 2020)
    Ultracold bialkali polar molecules play a leading part at the frontline of quantum physics. They recently attract a lot of attention in the field of ultracold quantum chemistry, quantum many-body physics and quantum ...
  • Gempel, M.W.; Hartmann, T.; Schulze, Torben A.; Voges, K.K.; Zenesini, Alessandro; Ospelkaus, Silke (Bristol : Institute of Physics Publishing, 2016)
    In this paper, we present an electrode geometry for the manipulation of ultracold, rovibrational ground state NaK molecules. The electrode system allows to induce a dipole moment in trapped diatomic NaK molecules with a ...
