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…

Anomalous Geometric Spin Hall Effect of Light?
Zhen-Lai Wang, Xiang-Song Chen
The geometric spin Hall effect of light (GSHEL), similar to the spin Hall effect of light, is also a spin-dependent shift of the centroid of light beam's intensity (energy flux), b…
