SI-Traceable Temperature Calibration Based on Optical Lattice Clocks
Jin Cao, Xiaotong Lu, Benquan Lu +1
We present a SI-traceable temperature calibration apparatus utilizing optical lattice clocks for precision metrology. The system employs a dual-blackbody radiation shield chamber w…
Lifetime Determination of the Metastable State in Sr from the Electric Dipole Matrix Element
Xiao-Tong Lu, Feng Guo, Yan-Yan Liu +6
We report a measurement of the radiative lifetime of the metastable state in Sr, which is coupled to the 5 ${}^{\rm…
Absolute frequency measurement of the 87Sr optical lattice clock at NTSC using International Atomic Time
Xiaotong Lu, Feng Guo, Yebing Wang +5
We report the absolute frequency measurement of the 5s2 1S0-5s5p 3P0 transition in 87Sr optical lattice clock (Sr1) at National Time Service Center (NTSC). Its systematic frequency…
Ab initio calculations of the hyperfine structure of 109Cd, 109Cd+ and reevaluation of the nuclear quadrupole moment Q(109Cd)
Benquan Lu, Xiaotong Lu, Tao Wang +1
Large scale ab initio calculations of the electric contribution (i.e. the electric field gradient) to the electric quadrupole hyperfine interaction constants for the $5p~^2P_{3…
Theoretical Calculation of the Quadratic Zeeman Shift Coefficient of the 3P0 clock state for Strontium Optical Lattice Clock
Benquan Lu, Xiaotong Lu, Jiguang Li +1
The quadratic Zeeman shift coefficient of 3P0 clock state for strontium is determined in theory and experiment. In theory, we derived the expression of the quadratic Zeeman shift o…
Measurement of the probe Stark shift of the 87Sr optical lattice clock using the frequency modulation spectroscopy
Qinfang Xu, Xiaotong Lu, Jingjing Xia +2
With the uncertainty of the optical clocks improving to the order of 10-18, the probe light used to detect the clock transition has demonstrated nonnegligible Stark shift, provokin…
