  • Mixing of 0(+) and 0(-) observed in the hyperfine and Zeeman structure of ultracold Rb-2 molecules 
    Deiss, Markus; Drews, Bjoern; Denschlag, Johannes Hecker; Tiemann, Eberhard (Bristol : IOP Publishing Ltd., 2015-08-10)
    We study the combination of the hyperfine and Zeeman structure in the spin-orbit coupled A(1)Sigma(+)(u) = b(3)Pi(u) complex of Rb-87(2). For this purpose, absorption spectroscopy at a magnetic field around B = 1000 G is ...
  • Roadmap on STIRAP applications 
    Bergmann, Klaas; Nägerl, Hanns-Christoph; Panda, Cristian; Gabrielse, Gerald; Miloglyadov, Eduard; Quack, Martin; Seyfang, Georg; Wichmann, Gunther; Ospelkaus, Silke; Kuhn, Axel; Longhi, Stefano; Szameit, Alexander; Pirro, Philipp; Hillebrands, Burkard; Zhu, Xue-Feng; Zhu, Jie; Drewsen, Michael; Hensinger, Winfried K.; Weidt, Sebastian; Halfmann, Thomas; Wang, Hai-Lin; Paraoanu, Gheorghe Sorin; Vitanov, Nikolay V.; Mompart, Jordi; Busch, Thomas; Barnum, Timothy J.; Grimes, David D.; Field, Robert W.; Raizen, Mark G.; Narevicius, Edvardas; Auzinsh, Marcis; Budker, Dmitry; Pálffy, Adriana; Keitel, Christoph H. (Bristol : Institute of Physics Publishing, 2019)
    STIRAP (stimulated Raman adiabatic passage) is a powerful laser-based method, usually involving two photons, for efficient and selective transfer of populations between quantum states. A particularly interesting feature ...
  • Towards ultracold polar NaK molecules and the investigation of dipolar quantum gases 
    Gempel, Matthias Walter (Hannover : Gottfried Wilhelm Leibniz Universität Hannover, 2016)
    [no abstract]
  • Type-II Zeeman Slower and design and construction of a cryogenic buffer gas beam source 
    Petzold, Maurice (Hannover : Institutionelles Repositorium der Leibniz Universität Hannover, 2018)
    Ultrakalte Moleküle versprechen neue Einsichten in diversen Forschungsfeldern die von kontrollierter ultrakalter Chemie über Präzisionsmessungen paritätsverletzender Effekte bis hin zu stark korrelierten dipolaren ...
  • Ultracold chemistry and its reaction kinetics 
    Richter, Florian (Hannover : Gottfried Wilhelm Leibniz Universität Hannover, 2015)
    [no abstract]
  • Ultracold chemistry and its reaction kinetics 
    Richter, Florian; Becker, Daniel; Bény, Cédric; Schulze, Torben A.; Ospelkaus, Silke; Osborne, Tobias J. (Bristol : IOP Publishing Ltd, 2015)
    We study the reaction kinetics of chemical processes occurring in the ultracold regime and systematically investigate their dynamics. Quantum entanglement is found to play a key role in driving an ultracold reaction towards ...
  • 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 ...
  • Universality of weakly bound dimers and Efimov trimers close to Li-Cs Feshbach resonances 
    Ulmanis, J.; Haefner, S.; Pires, R.; Kuhnle, E. D.; Weidemueller, M.; Tiemann, Eberhard (Bristol : IOP Publishing Ltd., 2015-05-07)
    We study the interspecies scattering properties of ultracold Li-Cs mixtures in their two energetically lowest spin channels in the magnetic field range between 800 and 1000 G. Close to two broad Feshbach resonances (FR) ...
  • 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 ...
  • A Zeeman slower for diatomic molecules 
    Petzold, M.; Kaebert, P.; Gersema, P.; Siercke, M.; Ospelkaus, S. (Bristol : Institute of Physics Publishing, 2018)
    We present a novel slowing scheme for beams of laser-coolable diatomic molecules reminiscent of Zeeman slowing of atomic beams. The scheme results in efficient compression of the one-dimensional velocity distribution to ...
