论文摘要
基于量子场理论，我们在弯曲的空间中为极化光子制定了Wigner函数和量子动力学理论，该光子接纳了协变量的恒定时间表矢量。从这个框架中，光子性手性/Zilch涡流效应在刚性旋转的坐标中再现。在空间不均匀的坐标中，我们得出了平衡中光子螺旋电流和能量电流的自旋霍尔效应。我们的派生表明，这种光子厅效应与洛伦兹的光子涡流效应有关，它们的传输系数相互匹配。
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.
