Abstract

In order to develop the microscopic theory of the multiphoton interaction of graphene with strong laser fields of arbitrary polarization, the analytical solution of established evolutionary equation for graphene single-particle density matrix was obtained revealing the generalized Rabi oscillations of Fermi-Dirac sea in the graphene. Creation of coherent superposition states of the particle-hole pairs in the graphene at the multiphoton resonant excitation by laser pulses of arbitrary polarizations and harmonics generation at the particle-hole annihilation from these superposition states are shown.
