Continuous-wave laser absorption spectroscopy of the Thorium-229 nucleus
I. Morawetz, T. Riebner, L. Toscani De Col +17
A low-energy nuclear transition in the isotope thorium-229 has been excited in thorium-doped crystals with laser light. This opens the perspective towards a highly stable and robus…
A thorium-229 optical nuclear clock with feedback loop
L. Toscani De Col, T. Riebner, I. Morawetz +25
The laser-accessible nuclear transition in the thorium-229 isotope has been identified as a promising candidate for the realization of an optical nuclear clock. Such a nuclear cloc…
metastable state of for a hyperfine-free nuclear clock
S. Sagar Maurya, V. Lal, J. Tiedau +2
We present measurements on a metastable state in with the electronic configuration . This is motivated by the prospect o…
High-accuracy multi-ion spectroscopy with mixed-species Coulomb crystals
J. Keller, H. N. Hausser, I. M. Richter +14
Multi-ion optical clocks offer the possibility of overcoming the low signal-to-noise ratio of single-ion clocks, while still providing low systematic uncertainties. We present simu…
In-Yb Coulomb crystal clock with systematic uncertainty
H. N. Hausser, J. Keller, T. Nordmann +17
We present a scalable mixed-species Coulomb crystal clock based on the transition in In. Yb ions are co-trapped and used f…
