论文摘要
在最近的工作中[A.〜 Yamaguchi等。 al,物理。莱特牧师。 {\ bf 123},113201(2019)] CD已被确定为晶格时钟的出色候选者。在这里,我们进行了进一步的时钟开发所需的计算,并对$ 5S ^2 \, ^1 \!S_0 $ - $ 5S5P \, ^3 \ 3 \!P_0 ^O $时钟过渡的较高级校正进行了评估。我们进行了磁性偶极子和电动四极极化的计算,以及$ 5S ^2 \, ^1 \!S_0 $和$ 5S5P \, ^3 \ 3 \!P_0 ^o $ $ $时钟状态的线性和圆形超极化能力。我们还评估了二阶的zeeman时钟过渡频移。
In the recent work [A.~Yamaguchi et. al, Phys. Rev. Lett. {\bf 123}, 113201 (2019)] Cd has been identified as an excellent candidate for a lattice clock. Here, we carried out computations needed for further clock development and made an assessment of the higher-order corrections to the light shift of the $5s^2\, ^1\!S_0$--$5s5p\, ^3\!P_0^o$ clock transition. We carried out calculations of the magnetic dipole and electric quadrupole polarizabilities and linear and circular hyperpolarizabilities of the $5s^2\, ^1\!S_0$ and $5s5p\, ^3\!P_0^o$ clock states at the magic wavelength and estimated uncertainties of these quantities. We also evaluated the second-order Zeeman clock transition frequency shift.
