Self-consistent theory of the second-harmonic generation in graphene — •Sergey Mikhailov — Institute of Physics, University of Augsburg, 86135 Augsburg, Germany

A self-consistent-field theory of the second-order nonlinear electromagnetic response of graphene is developed. The second-order polarizability and the corresponding second-order self-consistent dielectric response function of graphene are calculated for the first time. The second harmonic generation in graphene is shown to be about two orders of magnitude stronger than in typical semiconductor structures. Under the conditions of 2D plasmon resonances the second harmonic radiation intensity is further increased by several orders of magnitude.
