摘要：

Nonlinear dynamics of the establishment of electron-hole coherent superposition states in graphene by multiphoton resonant excitation of interband transitions in laser fields is considered. The single-particle time-dependent density matrix for such a quantized system is calculated in the multiphoton resonant approximation. The dependence of Rabi oscillations of the Fermi-Dirac sea in graphene on the time, momentum, and photon number at multiphoton laser excitation is analyzed.
