摘要：
The dynamic electric dipole polarizabilities of the 5s2 1S0, 5s5p3P0, and 5s5p 3P2 states for Cd atoms are calculated using the relativistic configuration interaction plus many -body perturbation theory method. The magic wavelengths for the 5s2 1S0 -* 5s5p 3P0 and 5s2 1S0 -* 5s5p 3P2 transitions within a range of 300-500 nm are identified. The possibility of achieving triple magic trapping for the transitions 5s2 1S0 -* 5s5p3P0 and 5s2 1S0 -* 5s5p 3P2 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 5s2 1S0 -* 5s5p 3P2 (Mi = +/- 2) and 5s2 1S0 -* 5s5p3P0 transitions.
