光在倾斜偏振器上的自旋霍尔效应
Spin-Hall effect of light at a tilted polarizer
摘要:
我们描述了光在倾斜的线性二向色性板(如通常的线性偏振器)上的自旋霍尔效应(以及角古斯-汉兴效应)。尽管倾斜偏振器处的自旋霍尔效应先前与光的几何自旋霍尔效应(其与常规自旋霍尔效应形成对比)相关联[J. Korger等人,物理修订信函112,113902(2014)],我们表明,该效应实际上是发生在倾斜各向异性板上的规则自旋霍尔效应的一个例子[K. Y. Bliokh等人,Optica 3,1039(2016)]。此外,我们的方法揭示了角自旋霍尔位移,这是缺席的“几何”的方法。我们用量子弱测量的方法在实验上验证了我们的理论。
英文摘要:
We describe the spin-Hall effect of light (as well as the angular Goos-Hänchen effect) at a tilted linear-dichroic plate, such as a usual linear polarizer. Although the spin-Hall effect at a tilted polarizer was previous associated with the geometric spin-Hall effect of light (which was contrasted to the regular spin-Hall effect) [J. Korger et al., Phys. Rev. Lett. 112, 113902 (2014)], we show that the effect is actually an example of the regular spin-Hall effect that occurs at tilted anisotropic plates [K. Y. Bliokh et al., Optica 3, 1039 (2016)]. Moreover, our approach reveals the angular spin-Hall shift, which is absent in the "geometric" approach. We verify our theory experimentally using the method of quantum weak measurements.
