Doubly magic optical trapping for Cs atom hyperfine clock transitions

Understand

We analyze doubly magic trapping of Cs hyperfine transitions including previously neglected contributions from the ground state hyperpolarizability and the interaction of the laser light and a static magnetic field.

• Extensive numerical searches do not reveal any doubly magic trapping conditions for any pair of hyperfine states.
• However, including the hyperpolarizability reveals light intensity insensitive traps for a wide range of wavelengths at specific intensities.
• We then investigate the possibility of using bichromatic trapping light fields.
