  • 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 ...
  • From ultraslow to fast lithium diffusion in the 2D ion conductor Li0.7TiS2 probed directly by stimulated-echo NMR and nuclear magnetic relaxation 
    Wilkening, Martin; Küchler, W.; Heitjans, Paul (College Park, ML : American Physical Society, 2006)
    7Li stimulated-echo NMR and classical relaxation NMR techniques are jointly used for the first time for a comprehensive investigation of Li diffusion in layer-structured Li0.7TiS2. One single 2D Li diffusion process was ...
  • Model-based feedback control of an ultrasonic transducer for ultrasonic assisted turning using a novel digital controller 
    Ille, I.; Twiefel, J. (Amsterdam : Elsevier, 2015)
    Ultrasonic turning has time variant parameters due to temperature effects and changing load conditions during the process. This results in a change of the resonance frequency and vibration amplitude. To realize constant ...
  • The status of GEO 600
