论文摘要
我们将几何光学元件扩展到弯曲时空上的圆形极化电磁波的转向顺序。这种转向级的几何光学光学扩展，其中通过插入精心选择的螺旋依赖性校正来修改常规的Eikonal函数，称为Spin Optics。当电磁波在弯曲时空中传播时，我们在自旋光学近似中得出了传播和极化方程。观察到了灯光轨迹与大地测量的偏振依赖性偏差，描述了重力自旋效应。我们还建立了一个类比，该比喻与凝结物理学的相关现象（光学马格努斯效应）。
We develop geometric optics expansion up to the subleading order for circularly polarized electromagnetic waves on curved spacetime. This subleading order geometric optics expansion, in which the conventional eikonal function is modified by inserting a carefully chosen helicity-dependent correction, is called spin optics. We derive the propagation and polarization equations in the spin optics approximation as electromagnetic waves travel in curved spacetime. Polarization-dependent deviation of the light ray trajectory from the geodesic, describing the gravitational spin Hall effect, is observed. We also establish an analogy with the related phenomena (optical Magnus effect) of condensed matter physics.
