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…
Degenerate Rabi spectroscopy of the Floquet engineered optical lattice clock
Wei-Xin Liu, Xiao-Tong Lu, Ting Li +4
Simulating physics with large SU(N) symmetry is one of the unique advantages of Alkaline-earth atoms.Introducing periodical driving modes to the system may provide more rich SU(N)…
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…
Floquet engineering Hz-Level Rabi Spectra in Shallow Optical Lattice Clock
Mo-Juan Yin, Tao Wang, Xiao-Tong Lu +4
Quantum metrology with ultra-high precision usually requires atoms prepared in an ultra-stable environment with well-defined quantum states. Thus, in optical lattice clock systems…
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…
