Tune-Out and Magic Wavelengths for Ground-State Na 23 K 40 Molecules

Abstract

We demonstrate a versatile, state-dependent trapping scheme for the ground and first excited rotational states of Na23K40 molecules. Close to the rotational manifold of a narrow electronic transition, we determine tune-out frequencies where the polarizability of one state vanishes while the other remains finite, and a magic frequency where both states experience equal polarizability. The proximity of these frequencies of only 10 GHz allows for dynamic switching between different trap configurations in a single experiment, while still maintaining sufficiently low scattering rates.
