Ultrafast terahertz nonlinear effect of Landau level transition in graphene

We performed THz pump-THz probe magneto-optical spectroscopy of monolayer epitaxial graphene under high magnetic field. We observed ultrafast THz-pump-induced reduction of Faraday rotation and bleaching of absorption associated with the Landau level transition.
