Anisotropic light shift and magic polarization of the intercombination line of dysprosium atoms in a far-detuned dipole trap

Abstract:

We characterize the anisotropic differential ac-Stark shift for the Dy 626 nm intercombination transition, induced in a far-detuned 1070 nm optical dipole trap, and observe the existence of a “magic polarization” for which the polarizabilities of the ground and excited states are equal. From our measurements we extract both the scalar and tensorial components of the dynamic dipole polarizability for the excited state, αsE=188(12)α0 and αtE=34(12)α0, respectively, where α 0 is the atomic unit ...
