Dynamic polarizabilities and triple magic trapping conditions for $5s^2~^1S_0\rightarrow 5s5p~^3P_{0,2}$ transitions of Cd atoms

Abstract

The dynamic electric dipole polarizabilities of the $5s^2~^1S_0$, $5s5p~^3P_{0}$, and $5s5p~^3P_2$ states for Cd atoms are calculated using the relativistic configuration interaction plus many-body perturbation theory method. The magic wavelengths for the $5s^2~^1S_0\rightarrow 5s5p~^3P_{0}$ and $5s^2~^1S_0\rightarrow 5s5p~^3P_2$ transitions within a range of 300-500 nm are identified. The possibility of achieving triple magic trapping for the transitions $5s^2~^1S_0\rightarrow5s5p~^3P_{0}$ and $5s^2~^1S_0\rightarrow5s5p~^3P_2$ is investigated. It is found that no common magic wavelength could be identified for achieving triple magic trapping with the linearly polarized light. However, if the degree of ellipticity is between $0.358$ and $1$, the triple magic trapping can be achieved at 419.88 nm for the $5s^2 ~ ^1S_0\rightarrow 5s5p~^3P_2$ ($M_{i}=\pm2$) and $5s^2~^1S_0\rightarrow5s5p~^3P_{0}$ transitions.
