A solid-state nuclear clock based on VUV absorption spectroscopy of $^{229}$ Th

Pengfei Wang, Xu-Fei Yin, Hanlin Wang +21

We demonstrate sustained operation of a solid-state thorium-229 nuclear clock using continuous-wave absorption at 148.4 nm. In a $^{229} Th : CaF_{2}$ crystal, we reso…

Absolute frequency measurement of a $^{176}$ 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…
