  • A long optical cavity for sub-Hertz laser spectroscopy 
    Amairi ep Pyka, Sana (Hannover : Gottfried Wilhelm Leibniz Universität Hannover, 2014)
    [no abstract]
  • Atomic clock comparisons with a 3e-16 uncertainty via geostationary satellites 
    Riedel, Franziska (Hannover : Institutionelles Repositorium der Leibniz Universität Hannover, 2021)
    Optical clocks are superior to all other clocks, reaching 1e-18 in their uncertainty. This makes them not only attractive for the field of fundamental research, like testing General Relativity or examining the variance of ...
  • Characterization and evaluation of GPS PPP techniques for optical clock comparisons 
    Leute, Julia (Hannover : Institutionelles Repositorium der Leibniz Universität Hannover, 2018)
    The suitability of an improved GPS time and frequency transfer technique, Integer Precise Point Positioning (IPPP), for the frequency comparison of optical clocks on the 1e−16 level was investigated. An optical fiber link ...
  • Development of a strontium optical lattice clock for the SOC mission on the ISS 
    Origlia, S.; Schiller, S.; Pramod, M.S.; Smith, L.; Singh, Y.; He, W.; Viswam, S.; Swierad, D.; Hughes, J.; Bongs, K.; Sterr, U.; Lisdat, C.; Vogt, S.; Bize, S.; Lodewyck, J.; Le Targat, R.; Holleville, D.; Venon, B.; Gill, P.; Barwood, G.; Hill, I.R.; Ovchinnikov, Y.; Kulosa, A.; Ertmer, Wolfgang; Rasel, Ernst Maria; Stuhler, J.; Kaenders, W.; SOC2 Consortium (2016)
    The ESA mission “Space Optical Clock” project aims at operating an optical lattice clock on the ISS in approximately 2023. The scientific goals of the mission are to perform tests of fundamental physics, to enable ...
