Abstract :
We develop a density-matrix formalism in the length gauge to simulate the nonlinear response on undoped graphene at terahertz frequencies. The generation of high harmonics is controlled by the strong interplay between intraband and interband dynamics. We present the differential signal, which reveals clear evidence of the high harmonic generation.
