论文摘要

我们考虑将磁光散射器的光学厚球形聚集体带有中央各向同性的,非极化的光源,放置在均匀的磁场中。光子大厅效应在介质内外诱导旋转的poynting载体。我们表明,电磁(轨道)角动量泄漏出来,并诱导与源和光子厅角度注入能力成正比的扭矩。这种效果代表了一类新型的光学现象,从而产生了从扩散磁通轨道的角动量。

We consider an optically thick spherical agglomerate of magneto-optical scatterers with a central isotropic, unpolarized light source, placed in a homogeneous magnetic field. The Photon Hall Effect induces a rotating Poynting vector, both inside and outside the medium. We show that electromagnetic (orbital) angular momentum leaks out and induces a torque proportional to the injection power of the source and the photon Hall angle. This effect represents a novel class of optical phenomena, generating angular momentum from diffusive magneto-transport.
