  • First international comparison of fountain primary frequency standards via a long distance optical fiber link 
    Guéna, J.; Weyers, S.; Abgrall, M.; Grebing, C.; Gerginov, V.; Rosenbusch, P.; Bize, Sebastien; Lipphardt, B.; Denker, H.; Quintin, N.; Raupach, S.M.F.; Nicolodi, D.; Stefani, F.; Chiodo, N.; Koke, S.; Kuhl, A.; Wiotte, F.; Meynadier, F.; Camisard, E.; Chardonnet, C.; Le Coq, Y.; Lours, M.; Santarelli, G.; Amy-Klein, A.; Le Targat, R.; Lopez, O.; Pottie, P.-E.; Grosche, G. (Bristol : Institute of Physics Publishing, 2017)
    We report on the first comparison of distant caesium fountain primary frequency standards (PFSs) via an optical fiber link. The 1415 km long optical link connects two PFSs at LNESYRTE (Laboratoire National de métrologie ...
  • Observation of phase fluctuations in elongated bose-einstein condensates 
    Dettmer, S.; Hellweg, D.; Ryytty, P.; Arlt, Jan J.; Ertmer, Wolfgang; Sengstock, K.; Petrov, D.S.; Shlyapnikov, G.V.; Kreutzmann, H.; Santos, Luis; Lewenstein, M. (American Physical Society, 2001)
    The occurrence of phase fluctuations due to thermal excitations in Bose-Einstein condensates (BECs) is studied for a variety of temperatures and trap geometries. We observe the statistical nature of the appearance of phase ...
  • Spin-noise spectroscopy under resonant optical probing conditions: Coherent and nonlinear effects 
    Horn, H.; Müller, G.M.; Rasel, Ernst Maria; Santos, Luis; Hübner, Jens; Oestreich, Michael (College Park, MD : American Physical Society, 2011)
    Highly sensitive Faraday rotation spectroscopy is used to measure the fluctuating magnetization noise of noninteracting rubidium atoms under resonant and nonresonant optical probing conditions. The spin-noise frequency ...
  • Spindynamik in quantenmechanischen Systemen : Untersuchungen an Rubidiumdampf und Zinkoxid 
    Horn, Hauke (Hannover : Gottfried Wilhelm Leibniz Universität Hannover, 2012)

  • Tunable dual-species Bose-Einstein condensates of 39K and 87Rb 
    Wacker, L.; Jørgensen, N.B.; Birkmose, D.; Horchani, R.; Ertmer, Wolfgang; Klempt, Carsten; Winter, N.; Sherson, J.; Arlt, Jan J. (College Park : American Physical Society, 2015)
    We present the production of dual-species Bose-Einstein condensates (BECs) of 39K and 87Rb. Preparation of both species in the |F=1,mF=−1⟩ state enabled us to exploit a total of three Feshbach resonances, which allows for ...
  • Wave packet echoes in the motion of trapped atoms 
    Buchkremer, F.B.J.; Dumke, R.; Levsen, H.; Birkl, G.; Ertmer, Wolfgang (American Physical Society, 2000)
    A new echo technique to access the coherent and dissipative dynamics of atomic wave packet oscillations in trapping potentials was experimentally and systematically validated. By using this technique, the coherence time ...
