  • An aluminum optical clock setup and its evaluation using Ca+ 
    Kramer, Johannes Albrecht (Hannover : Institutionelles Repositorium der Leibniz Universität Hannover, 2023)
    This thesis reports about the progress of the aluminum ion clock that is set up at the German National Metrological Institute, Physikalisch-Technische Bundesanstalt (PTB) in Braunschweig. All known relevant systematic ...
  • Development and characterization of a linear ion trap for an improved optical clock performance 
    Burgermeister, Tobias (Hannover : Institutionelles Repositorium der Leibniz Universität Hannover, 2019)
    Single ion frequency standards have demonstrated in several experiments excellent results and are approaching fractional frequency uncertainties of 10^-18. As dominant contributions to the uncertainty are linked to the ion ...
  • Gravity field modelling for optical clock comparisons 
    Denker, Heiner; Timmen, Ludger; Voigt, Christian (Prague : International Union of Geodesy and Geophysics (IUGG), 2015)
    A coordinated programme of clock comparisons is carried out within the EMRP-funded project “International Timescales with Optical Clocks” (ITOC), aiming at a validation of the uncertainty budgets of the new optical clocks ...
  • Quadrupole transitions and quantum gates protected by continuous dynamic decoupling 
    Martínez-Lahuerta, V.J.; Pelzer, L.; Dietze, K.; Krinner, L.; Schmidt, P.O.; Hammerer, K. (Philadelphia, PA : IOP Publishing, 2023)
    Dynamical decoupling techniques are a versatile tool for engineering quantum states with tailored properties. In trapped ions, nested layers of continuous dynamical decoupling (CDD) by means of radio-frequency field dressing ...
  • Ultra-stable laser based on a cryogenic single-crystal silicon cavity 
    Hagemann, Christian (Hannover : Gottfried Wilhelm Leibniz Universität Hannover, 2013)

  • Using quantum optical sensors for determining the Earth’s gravity field from space 
    Müller, Jürgen; Wu, Hu (Berlin [u.a.] : Springer, 2020)
    Quantum optical technology provides an opportunity to develop new kinds of gravity sensors and to enable novel measurement concepts for gravimetry. Two candidates are considered in this study: the cold atom interferometry ...
