The Hall effects of vortex light in optical materials
Wei-Si Qiu, Li-Li Yang, Dan-Dan Lian +1
For light, its spin can be independent of the spatial distribution of its wave function, whereas its intrinsic orbital angular momentum does depend on this distribution. This diffe…

Extraordinary spin density and energy back-flow under interference
Zhen-Lai Wang, Dan-Dan Lian, Xiang-Song Chen
A novel phenomenon was reported recently that the "local optical spin density" based on Poynting vector might be counter-intuitively opposite to the integrated spin orientation whi…
