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…
Improved magneto-optical trapping of Ca
Michael Mills, Prateek Puri, Yanmei Yu +3
We investigate the limiting factors in the standard implementation of the Ca magneto-optical trap. We find that intercombination transitions from the 4s5p 1P1 state used to repump…
Determination of Landé factor and Zeeman coefficients in ground-state Yb and their applications to quantum frequency standards
Jize Han, Benquan Lu, Yanmei Yu +5
We report the determination of the Landé factor and Zeeman coefficients for the ground-state of Yb, relevant to microwave quantum frequency standards (QFSs). The…
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 $ ^{…
Transition rates and radiative lifetimes of Ca I
Yanmei Yu, Andrei Derevianko
We tabulate spontaneous emission rates for all possible 811 electric-dipole-allowed transitions between the 75 lowest-energy states of Ca I. These involve the (), $4s…
Precision determination of the excited-state hyperfine splitting of Cadmium ions
Ying Zheng, Yanmei Yu, Yiting Chen +4
Precision determination of the hyperfine splitting of cadmium ions is essential to study space-time variation of fundamental physical constants and isotope shifts. In this work, we…
