摘要:

本文利用光学度规研究了偏振光在非均匀介质中的传播。我们发现,光子的演化除了受自旋轨道相互作用的影响外,还受光子自旋相互作用的影响。由于自旋-自旋相互作用,偏振光的光线轨迹沿着介质的不均匀性梯度方向存在小的偏转。它不同于光子自旋霍尔效应所描述的横向偏转。

英文摘要:

By means of the optical metric, we investigate the propagation of a polarized light in an inhomogeneous medium in this paper. We find that the evolution of photons is affected by the spin-spin interaction of photons, besides the spin-orbit interaction. Due to the spin-spin interaction, there is a small deflection of the ray trajectory of the polarized light along the direction of the inhomogeneity gradient of the medium. It is different from the transverse deflection described by the spin Hall effect of photons.
