A nuclear clock synchronized to Th
Beichen Huang, Gaowei Yan, Qi Xiao +37
Atomic clocks have made time and frequency the most precisely measured quantities in physics, progressing from microwave standards that realize the SI second to optical clocks with…
A continuous-wave vacuum ultraviolet laser for the nuclear clock
Qi Xiao, Gleb Penyazkov, Xiangliang Li +14
The exceptionally low-energy isomeric transition in Th at around 148.4 nm offers a unique opportunity for coherent nuclear control and the realisation of a nuclear clock. R…
Absolute frequency measurements with a robust, transportable ^{40}Ca^{+} optical clock
Huaqing Zhang, Yao Huang, Baolin Zhang +9
We constructed a transportable 40Ca+ optical clock (with an estimated minimum systematic shift uncertainty of 1.3*10^(-17) and a stability of 5*10^(-15)/sqrt{tau} ) that can operat…
Development and Evaluation of a Narrow Linewidth Laser System for 171Yb+ E2 Transition
Yani Zuo, Shiying Cao, Shaoyang Dai +9
We report the construction and characterization of a narrow-linewidth laser system to interrogate the E2 clock transitions at 436 nm of ytterbium ions trapped in end-cap traps. The…
Inelastic collisions and density-dependent excitation suppression in a Sr optical lattice clock
Michael Bishof, Michael J Martin, Matthew D. Swallows +5
We observe two-body loss of Sr atoms trapped in a one-dimensional optical lattice. We measure loss rate coefficients for atomic samples between 1 and 6 K that…
