  • Fast transport of Bose-Einstein condensates 
    Torrontegui, E.; Chen, Xi; Modugno, M.; Schmidt, S.; Ruschhaupt, A.; Muga, J. G. (Bristol : IOP Publishing Ltd., 2012)
    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 ...
  • Hexapole-compensated magneto-optical trap on a mesoscopic atom chip 
    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 ...
  • Neuartige Kühlmethoden zur Erzeugung ultrakalter Ca-Atome 
    Binnewies, Tomas (Hannover : Universität, 2001)
    [no abstract]
  • Perspective on quantum bubbles in microgravity 
    Lundblad, Nathan; Aveline, David C.; Balaž, Antun; Bentine, Elliot; Bigelow, Nicholas P.; Boegel, Patrick; Efremov, Maxim A.; Gaaloul, Naceur; Meister, Matthias; Olshanii, Maxim; Sá de Melo, Carlos A. R.; Tononi, Andrea; Vishveshwara, Smitha; White, Angela C.; Wolf, Alexander; Garraway, Barry M. (Philadelphia, PA : IOP Publishing, 2023)
    Progress in understanding quantum systems has been driven by the exploration of the geometry, topology, and dimensionality of ultracold atomic systems. The NASA Cold Atom Laboratory (CAL) aboard the International Space ...
  • Photoassociation of 40Ca at high laser intensities 
    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 ...
  • An ultracold gas of bosonic 23Na39K ground-state molecules 
    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 ...
  • Universal quantum computation and quantum error correction with ultracold atomic mixtures 
    Kasper, Valentin; González-Cuadra, Daniel; Hegde, Apoorva; Xia, Andy; Dauphin, Alexandre; Huber, Felix; Tiemann, Eberhard; Lewenstein, Maciej; Jendrzejewski, Fred; Hauke, Philipp (Philadelphia, PA : IOP Publishing, 2022)
    Quantum information platforms made great progress in the control of many-body entanglement and the implementation of quantum error correction, but it remains a challenge to realize both in the same setup. Here, we propose ...
  • Versatile electric fields for the manipulation of ultracold NaK molecules 
    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 ...
