A nuclear clock based on Th
Beichen Huang, Gaowei Yan, Qi Xiao +35
Atomic clocks have made time and frequency the most precisely measured quantities in physics, progressing from microwave standards that realize the SI second to optical clocks that…
Theoretical study of transition matrix elements in cadmium for vacuum-ultraviolet generation in Th nuclear clock applications
Gleb Penyazkov, Yanmei Yu, Leonid V. Skripnikov +1
The relativistic Fock-space coupled-cluster methods are applied to the cadmium atom. A large number of transition energies and matrix elements are calculated for the $ ^{…
A cryogenic Paul trap for probing the nuclear isomeric excited state Th
Daniel Moritz, Kevin Scharl, Markus Wiesinger +16
While laser excitation of the nuclear isomeric transition in Th has been recently achieved for thorium atoms embedded in large-bandgap crystals, laser excitation and charac…
A continuous-wave vacuum ultraviolet laser for the nuclear clock
Qi Xiao, Gleb Penyazkov, Xiangliang Li +14
The exceptionally low-energy isomeric transition in Th at around 148.4 nm offers a unique opportunity for coherent nuclear control and the realisation of a nuclear clock. R…
Proposal for the generation of continuous-wave vacuum ultraviolet laser light for Th-229 isomer precision spectroscopy
Qi Xiao, Gleb Penyazkov, Ruihan Yu +6
We propose to generate continuous-wave vacuum ultraviolet (VUV) laser light at 148.4 nm using four-wave mixing in cadmium vapor for precision spectroscopy of the Th-229 isomer tran…
