In this paper we apply quench cooling to a single Ytterbium ion. We study the optimal parameters for fast and deep cooling in the sideband, intermediate and semi-classical cooling regime which can be flexibly tuned via the quench laser intensity. Moreover, we discuss the non-thermal distribution of...

Giving a throughout overview on the experimental setup of the multi-ion indium clock, her thesis serves as a good reference for new members of our team and the scientific community interested in optical clocks. Finishing her Ph.D. studies was a and also a personal achievement. Congratulations!

In attempts to unify all fundamental forces in a single quantum consistent theory it has been suggested that Lorentz symmetry is violated. We have investigated the principle of local Lorentz invariance in a single trapped Yb⁺ ion by comparing spatially oriented atomic orbitals. The highly...
