Evaluation of blackbody radiation shift with temperature associated fractional uncertainty at 10E-18 level for 40Ca+ ion optical clock

Ping Zhang, Jian Cao, Hua-lin Shu +7

In this paper, blackbody radiation (BBR) temperature rise seen by the $^{40}$ Ca $^{+}$ ion confined in a miniature Paul trap and its uncertainty have been evaluated via finite-element…

A transportable 40Ca+ single-ion clock with $7.7 \times 1 0^{- 17}$ systematic uncertainty

Jian Cao, Ping Zhang, Junjuan Shang +6

A transportable optical clock refer to the $4 s^{2} S_{1/2} - 3 d^{2} D_{5/2}$ electric quadrupole transition at 729 nm of single $^{40} C a^{+}$ trapped in mini Paul trap has been developed. Th…
