论文摘要
我们计算并测量$ 6S^2 {} \，^1S_0-6S6P \，{}^3p_1 $中性ytterbium Atom的隔离过渡的魔术波长。使用\ textIt {ab Initio}配置交互（CI） +全阶方法执行计算。测量是通过光学偶极陷阱中冷原子上的激光光谱进行的。对于$π$过渡（$δm= 0 $），魔术波长确定为1035.68（4）nm，对于$σ$ transitions（$ | |δm| = 1 $）的1036.12（3）nm与计算值的一致。当将陷阱波长调谐到魔术波长附近时，狭窄的探测过渡上的激光冷却可以在光学偶极陷阱中获得更好的原子。
We calculate and measure the magic wavelengths for the $6s^2{}\,^1S_0-6s6p\,{}^3P_1$ intercombination transition of the neutral ytterbium atom. The calculation is performed with the \textit{ab initio} configuration interaction (CI) + all-order method. The measurement is done with laser spectroscopy on cold atoms in an optical dipole trap. The magic wavelengths are determined to be 1035.68(4) nm for the $π$ transition ($Δm = 0$) and 1036.12(3) nm for the $σ$ transitions ($|Δm| = 1$) in agreement with the calculated values. Laser cooling on the narrow intercombination transition could achieve better results for atoms in an optical dipole trap when the trap wavelength is tuned to near the magic wavelength.
