Photon-spin-dependent contribution to the -odd Faraday rotation effect for atoms

Abstract

The photon-spin-dependent (PS) contribution to the ordinary Faraday effect—optical rotation in an external magnetic field is well known. This contribution is proportional to factor where is the photon spin. Recently a -odd Faraday effect—optical rotation in an external electric field —was discussed as a promising tool for observation of the electron electric dipole moment in the intra-cavity absorption spectroscopy. In the present paper, we introduce the PS contribution to the -odd Faraday rotation effect. This contribution is proportional to and has to be taken into account in the calculations of the -odd Faraday effect.
