Abstract

In the physics of quantum Hall effect, static (DC) conductions are usually studied. Recently Morimoto, et al. has proposed that when we shine a terahertz light to the sample we should have an "optical Hall effect", a novel concept, where the optical Hall response retains, surprisingly, step-like structures arising from localization physics in AC. The effect is predicted to be observable as a Faraday rotation of polarized lights with the relevant photon energy in THz regime. The effect has subsequently been experimentally observed by Ikebe, et al. with terahertz Faraday rotation for a two-dimensional electron system in GaAs/AlGaAs. We give a brief review both theoretically and experimentally.
