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 ...
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 ...
