Dominant role of two-photon vertex in nonlinear response in two-dimensional Dirac systems
Abstract We show that the standard concepts of nonlinear response to electromagnetic fields break down in two-dimensional Dirac systems, like graphene, in the quantum regime close to the Dirac point. We present a compelling many-body theory for nonlinear transport focusing on disorder scattering as...
