AI 中文摘要
我们研究了在弯曲时空中与轴矢标量场耦合的高频电磁波的传播。通过应用有效作用量方法，我们超越了标准几何光学极限，推导了适用于任意弯曲时空和任意轴矢分布的轴矢 - 麦克斯韦理论的自旋光学方程。这些方程使我们能够分析光子与轴矢场及时空曲率相互作用产生的与螺旋度相关的对光子轨迹的修正。我们给出了代表性例子，以展示在存在轴矢场时，由于自旋光学效应，光轨迹如何偏离零测地线。
英文摘要
We study the propagation of high-frequency electromagnetic waves coupled to an axionic scalar field in curved spacetime. By applying the effective action approach, we go beyond the standard geometric optics limit and derive spinoptics equations for the axion--Maxwell theory that are valid for arbitrary curved spacetimes and arbitrary axion profiles. These equations allow us to analyze helicity-dependent corrections to photon trajectories arising from the photon's interactions with both the axion field and spacetime curvature. We present representative examples to demonstrate how light trajectories deviate from null geodesics due to spinoptics effects in the presence of an axion field.
