Precision measurement of the $^{176} Lu^{+}$ $^{3} D_{1}$ microwave clock transitions

M. D. K. Lee, Qi Zhao, Qin Qichen +4

We report precision measurement of the unperturbed $^{3} D_{1}$ microwave transition frequencies in $^{176} Lu^{+}$ to a fractional uncertainty of $4 \times 1 0^{- 14}$ . We find t…

Zeeman Degenerate Sideband Cooling in $^{176}$ Lu $^{+}$

Qin Qichen, Qi Zhao, M. D. K. Lee +4

We explore degenerate Raman sideband cooling in which neighboring Zeeman states of a fixed hyperfine level are coupled via a two-photon Raman transition. The degenerate coupling be…

Absolute frequency measurement of a Lu $^{+}$ $(^{3} D_{1})$ optical frequency standard via link to international atomic time

Zhao Zhang, Qi Zhao, Qin Qichen +4

We report on an absolute frequency measurement of the $Lu^{+} (^{3} D_{1})$ standard frequency which is defined as the hyperfine-average of $^{1} S_{0}$ to $^{3} D_{1}$ o…
