Spin Hall effect of light in graphene

We present a theoretical and experimental investigation of the spin Hall effect (SHE) of light in graphene. When a light beam impinges onto graphene-prism interface near Brewster angle, an enhanced and switchable spin-dependent splitting can be detected via the signal enhancement technique known from weak measurements. Our preliminary experimental results show that the SHE of light can become an advantageous metrology tool for characterizing the refractive index of graphene. In addition, the SHE of light may have a potential of probing the spatial accumulations of spin electrons in the graphene, which builds a bridge between electronic SHE and photonic SHE.
