本文将量子化偏振光在磁光操纵原子系综中的双折射作为光的广义Stern-Gerlach效应来研究。为了解释这种工程双折射显微镜，我们推导出一个有效的薛定谔方程的空间运动的两个正交偏振的组件，其表现为一个自旋的有效磁矩导致Stern-Gerlach分裂在一个不均匀的磁场。我们表明，电磁感应透明机制可以增强磁光Stern-Gerlach效应的光的存在下，控制场的横向空间分布和非均匀磁场。
We study the birefringence of quantized polarized light in a magneto-optically manipulated atomic ensemble as a generalized Stern-Gerlach effect of light. To explain this engineered birefringence microscopically, we derive an effective Shrodinger equation for the spatial motion of two orthogonally polarized components, which behave as a spin with an effective magnetic moment leading to a Stern-Gerlach split in a nonuniform magnetic field. We show that the electromagnetically-induced-transparency mechanism can enhance the magneto-optical Stern-Gerlach effect of light in the presence of a control field with a transverse spatial profile and a nonuniform magnetic field.
