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…
Toward nanophotonic platforms for solid-state Th nuclear clocks
Sandro Kraemer, Karen Mamian, Toby Bi +18
While the Th nuclear isomer has recently been observed and laser-excited, converting optical nuclear manipulation into a chip-scale solid-state frequency standard remains a…
Laser Mössbauer spectroscopy of ^{229}Th
Takahiro Hiraki, Takahiko Masuda, Sayuri Takatori +24
Mössbauer spectroscopy is widely used in biochemistry, geology, and solid-state physics to obtain structural information on materials. Here, we extend this technique into the optic…
Laser-Induced Quenching of the Th-229 Nuclear Clock Isomer in Calcium Fluoride
F. Schaden, T. Riebner, I. Morawetz +11
The 10-minute radiative lifetime of the first excited Th nuclear state in ionic crystals provides narrow spectroscopic linewidths, enabling the realization of a soli…
