    Preparing highly charged ions (HCIs) in a cold and strongly localized state is of particular interest for frequency metrology and tests of possible spatial and temporal variations of the fine structure constant. Our versatile ...
  • Kaczmarczyk, J.; Weimer, Hendrik; Lemeshko, Mikhail (Bristol : Institute of Physics Publishing, 2016)
    The Fermi-Hubbard model is one of the key models of condensed matter physics, which holds a potential for explaining the mystery of high-temperature superconductivity. Recent progress in ultracold atoms in optical lattices ...
  • 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 ...

  • Friebe, J.; Riedmann, M.; Wübbena, T.; Pape, A.; Kelkar, H.; Ertmer, Wolfgang; Terra, O.; Sterr, Uwe; Weyers, S.; Grosche, G.; Schnatz, H.; Rasel, Ernst Maria (Bristol : IOP Publishing Ltd., 2011)
    We perform Ramsey-Bordé spectroscopy on laser-cooled magnesium atoms in free fall to measure the 1S 0→ 3P 1 intercombination transition frequency. The measured value of 655 659 923 839 730 (48) Hz is consistent with our ...
  • Hinderthür, H.; Ruschewitz, F.; Lohe, H.-J.; Lechte, S.; Sengstock, K.; Ertmer, Wolfgang (American Physical Society, 1999)
    We report on experiments of multiple-beam atom interferometry in the time domain. Laser-cooled and trapped atoms interact with atomic "multiple beam splitters" realized by time sequences of resonant laser pulses. The output ...
  • 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 ...
