  • Doppler Cooling and Trapping on Forbidden Transitions 
    Binnewies, T.; Wilpers, G.; Sterr, U.; Riehle, F.; Helmcke, J.; Mehlstäubler, T.E.; Rasel, Ernst Maria; Ertmer, Wolfgang (American Physical Society, 2001)
    Ultracold atoms at temperatures close to the recoil limit have been achieved by extending Doppler cooling to forbidden transitions. A cloud of 40Ca atoms has been cooled and trapped to a temperature as low as 6μK by operating ...
  • Engineering interactions and anyon statistics by multicolor lattice-depth modulations 
    Cardarelli, Lorenzo; Greschner, Sebastian; Santos, Luis (College Park, MD : American Physical Society, 2016)
    We show that a multicolor modulation of the depth of an optical lattice allows for a flexible independent control of correlated hopping, occupation-dependent gauge fields, effective on-site interactions without Feshbach ...
  • Generalized quantum mean-field systems and their application to ultracold atoms 
    Trimborn-Witthaut, Friederike Annemarie (Hannover : Gottfried Wilhelm Leibniz Universität Hannover, 2011)
    [no abstract]
  • Influence of the particle number on the spin dynamics of ultracold atoms 
    Heinze, Jannes; Deuretzbacher, Frank; Pfannkuche, Daniela (College Park, MD : American Physical Society, 2010)
    We study the dependency of the quantum spin dynamics on the particle number in a system of ultracold spin-1 atoms within the single-spatial-mode approximation. We find, for all strengths of the spin-dependent interaction, ...
  • A Laser System for Gray-Molasses Cooling on the D1 Transition of an Atomic Gas of 39K 
    Shammout, Baraa (Hannover : Gottfried Wilhelm Leibniz Universität, 2020)
    In this work we present the design and the construction of a laser system for cooling an atomic gas of potassium 39K on the D1-Line by gray molasses technique. The seed laser is an Interference-filter-stabilized external-cavity ...
  • One dimensional 4-component alkali fermions 
    Jaramillo Salazar, Juan Diego (Hannover : Gottfried Wilhelm Leibniz Universität Hannover, 2014)
    [no abstract]
  • Preparation of Ultracold Atom Clouds at the Shot Noise Level 
    Gajdacz, M.; Hilliard, A.J.; Kristensen, M.A.; Pedersen, P.L.; Klempt, Carsten; Arlt, Jan J.; Sherson, J.F. (College Park : American Physical Society, 2016)
    We prepare number stabilized ultracold atom clouds through the real-time analysis of nondestructive images and the application of feedback. In our experiments, the atom number N similar to 10(6) is determined by high ...
  • 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 ...
