Ab Initio Relativistic Study of Formation of Ultracold Polar Molecules
Abstract
We determine conditions for effective quantum control over internal and external degrees of freedom of polar alkali-metal molecules in an optical trap. We calculate the dynamic molecular polarizability of KRb and RbCs as a function of laser frequency. The real part of the molecular polarizibility determines the depth of the trapping potential while the imaginary part contributes to laser-induced decoherences. Our results show that a relatively modest laser intensity is needed for strong confinement of polar molecules in an optical trap and that decoherence effects are manageable. More complete information on the scientific progress for the period of the extension is given in the Attachment.
