Description

Optical atomic clocks are today’s most accurate time-keeping devices. They achieve stunning systematic frequency uncertainties in the range of 10^-18, corresponding to an error of 1 second in 30 billion years. An even improved accuracy is expected to be achieved by a nuclear optical clock, since the nucleus is significantly less sensitive to external influences than the atomic shell.

In this talk I will give an overview over the recent progress that has been made toward the development of a nuclear optical clock based on Thorium-229. I will introduce several experiments that are currently in preparation aiming towards this goal. Finally, I will introduce the investigations underway within the framework of the BMBF-funded project “NuQuant”.
