Abstract
We study high-order harmonic generation by optically driven one- and two-dimensional hydrogen-like atoms formed by Coulomb impurities in graphene. The time-dependent Dirac equations with Coulomb plus time-periodic monochromatic field potentials are solved for both cases. Such characteristics of the optical high harmonic generation, as average dipole moment and high harmonic generation spectra, are computed. A sketch for table-top experimental realization of the considered models is proposed.
