  • Analyse und Entwurf von Hochbitratigen Clock-and-Data-Recovery Schaltungen in CMOS-Technologie [Analysis and design of high-bitrate Clock-and-Data-Recovery circuits in CMOS technology] 
    Bremer, J.-K.; Zemko, C.; Schmackers, J.; Mathis, Wolfgang (Göttingen : Copernicus GmbH, 2007)
    This paper presents a novel realization concept for Clock-and-Data-Recovery circuits. Our Design uses a nonlinear phase detector architecture, which is based on the Alexander phase detection method. In order to ensure ...
  • Atom-interferometric test of the universality of gravitational redshift and free fall 
    Ufrecht, Christian; Di Pumpo, Fabio; Friedrich, Alexander; Roura, Albert; Schubert, Christian; Schlippert, Dennis; Rasel, Ernst M.; Schleich, Wolfgang P.; Giese, Enno (College Park, MD : APS, 2020)
    Introducing internal-state transitions simultaneously on each branch of a light-pulse atom interferometer, we propose a scheme that is concurrently sensitive to both violations of the universality of free fall and gravitational ...
  • 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 ...
  • Interference of clocks: A quantum twin paradox 
    Loriani, Sina; Abend, Sven; Gaaloul, Naceur; Meiners, Christian; Schubert, Christian; Tell, Dorothee; Wodey, Étienne; Ertmer, Wolfgang; Schlippert, Dennis; Rasel, Ernst M. (Washington : American Association for the Advancement of Science (A A A S), 2019)
    The phase of matter waves depends on proper time and is therefore susceptible to special-relativistic (kinematic) and gravitational (redshift) time dilation. Hence, it is conceivable that atom interferometers measure ...
  • Multi-mode ground state cooling of trapped ions 
    Scharnhorst, Nils (Hannover : Gottfried Wilhelm Leibniz Universität Hannover, 2018)
    [no abstract]
  • Quantum Algorithmic Readout in Multi-Ion Clocks 
    Schulte, M.; Lörch, N.; Leroux, I.D.; Schmidt, Piet O.; Hammerer, K. (College Park, MD : American Physical Society, 2016)
    Optical clocks based on ensembles of trapped ions promise record frequency accuracy with good short-term stability. Most suitable ion species lack closed transitions, so the clock signal must be read out indirectly by ...
  • Sub-Microsecond Time Synchronization for Network-Connected Microcontrollers 
    Schleusner, Jens; Fahnemann, Christian; Pfleiderer, Richard; Blume, Holger (Piscataway, NJ : IEEE, 2024)
    This paper presents a bare-metal implementation of the IEEE 1588 Precision Time Protocol (PTP) for network-connected microcontroller edge devices, enabling sub-microsecond time synchronization in automotive networks and ...
