考虑动量空间中的Berry曲率，导出了光波包的半经典运动方程。这个方程自然地描述了轨道角动量和自旋角动量之间的相互作用，即，光的总角动量守恒。这导致波包运动垂直于介电常数梯度的偏移，即，光的偏振霍尔效应。还提出了在光子晶体中增强这种效应。
We derive the semiclassical equation of motion for the wave packet of light taking into account the Berry curvature in momentum-space. This equation naturally describes the interplay between orbital and spin angular momenta, i.e., the conservation of the total angular momentum of light. This leads to the shift of wave-packet motion perpendicular to the gradient of the dielectric constant, i.e., the polarization-dependent Hall effect of light. An enhancement of this effect in photonic crystals is also proposed.
