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…
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…
Role of hyperfine interaction in Landé -factors of clock states
Tingxian Zhang, Benquan Lu, Jiguang Li +4
In the weak-magnetic-field approximation, we derived a general expression of hyperfine-induced Landé -factors. By using this formula and the multi-configuration Dirac-Hartree-Fo…
Reevaluation of the nuclear electric quadrupole moment for 87Sr by hyperfine structures and relativistic atomic theory
Benquan Lu, Tingxian Zhang, Hong Chang +3
The values of nuclear electric quadrupole moment are different by about 7% for 87Sr nucleus between the recommended value [N. J. Stone, At. Data Nucl. Data Tables 111-112, 1 (2016)…
High-order sideband effect with two-level atoms in a shaken optical lattice
Mo-Juan Yin, Jie-Yun Yan, Qin-Fang Xu +7
The system of cold two-level atoms inside an optical lattice potential has been used to simulate various models encountered in fundamental and condensed-matter physics. When the op…
Exploration of the magnetic-field-induced ~~-~~ forbidden transition in bosonic Sr atom
Benquan Lu, Yebing Wang, Jianxin Han +3
We presented experimental and theoretical studies of the effect of an external magnetic field on the forbidden transition in the bosonic Sr atom. In our ultra-cold atomic system, t…
