论文摘要
当线性极化的电磁/重力波通过重力相互作用从旋转点源散射时，框架拖拉效应表现为极化方向旋转，这一效果也称为引力法拉第旋转。将一般相对论视为有效的场理论，Faraday旋转角及其量子校正是使用散射幅度计算的。尽管经典的旋转角度是从等价原理中预期的，但发现量子校正在电磁波和重力波之间是不同的，这支持了早期的研究，即等效原理的某些表述可能需要在量子状态下重新制定。
Frame-dragging effect manifests itself as polarization direction rotation when linearly polarized electromagnetic/gravitational wave scatters from a spinning point source through gravitational interactions, an effect also known as the gravitational Faraday rotation. Treating general relativity as an effective field theory, the Faraday rotation angle and its quantum corrections are computed using scattering amplitudes. While the classical rotation angle is universal as expected from the equivalence principle, the quantum corrections are found to be different between electromagnetic and gravitational waves, supporting earlier studies that some formulations of the equivalence principle may need reformulation in the quantum regime.
