Spin-momentum locked interaction between guided photons and surface electrons in topological insulators
Whether topologically protected electron moving and photon moving can couple each other remains an interesting question. Here, Luo et al. report reversion of photon spin and the direction of the photocurrent in a topological insulator by changing light propagation direction.
