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.

光子自旋对原子奇数法拉第旋转效应的贡献

光子自旋相关 (PS) 对普通法拉第效应的贡献 - 外部磁场中的光学旋转是众所周知的。这种贡献是成正比的因素，其中是光子自旋。最近，人们讨论了奇法拉第效应——在外部电场中的旋光——作为观察腔内吸收光谱中电子电偶极矩的有前途的工具。在本文中，我们介绍了 PS 对奇法拉第旋转效应的贡献。这种贡献与奇法拉第效应的计算成正比，并且必须在计算中加以考虑。
