基于量子场论，给出了弯曲时空中具有协变常数类时矢量的偏振光子的Wigner函数和量子动力学理论。在此框架下，光子手性/齐旋效应在刚性旋转坐标系中再现。在空间非均匀坐标系下，导出了平衡状态下的光子螺旋电流和能量电流的自旋霍尔效应。我们的推导表明，这种光子霍尔效应通过洛伦兹不变性与光子涡旋效应相关，并且它们的输运系数相互匹配。
Based on quantum field theory, we formulate the Wigner function and quantum kinetic theory for polarized photons in curved spacetimes which admit a covariantly constant timelike vector. From this framework, the photonic chiral/zilch vortical effects are reproduced in a rigidly rotating coordinate. In a spatially inhomogeneous coordinate, we derive the spin Hall effect for the photon helicity current and energy current in equilibrium. Our derivation reveals that such photonic Hall effect are related to the photonic vortical effect via the Lorentz invariance and their transport coefficients match each other.
