Magic wavelengths for trapping the alkali-metal atoms with circularly polarized light

Magic wavelengths for the Li, Na, and K alkali-metal atoms are determined using the circularly polarized light for the ns-np(1/2,3/2) transitions, with n denoting their ground-state principal quantum numbers, by studying their differential ac dynamic polarizabilities. These wavelengths for all possible sublevels are given linearly as well as circularly polarized lights and are further compared with the available results for the linearly polarized light. The present study suggests that it is possible to carry out state-insensitive trapping of different alkali-metal atoms using the circularly polarized light. DOI: 10.1103/PhysRevA.87.023402
