Absolute frequency measurement of the $^{176}$ Lu $^{+} (^{3} D_{1})$ standard against the NRC-FCs2 fountain with $2.6 \times 1 0^{- 16}$ uncertainty

K. J. Arnold, Bin Jian, Zhao Zhang +6

We report an improved absolute frequency measurement of the $^{176}$ Lu $^{+} (^{3} D_{1})$ optical frequency standard, evaluated via a remote link to the NRC-FCs2 caesium fount…

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…
