▎ 摘　　要

Ultrafast quantum dynamics of interband transitions in monolayer graphene initiated by strong laser radiation is investigated. A microscopic theory describing nonlinear interaction beyond the Dirac cone approximation and applicable to the full Brillouin zone of the hexagonal nanostructure with tight-binding electronic states is developed. Coherent effects toward the control of macroscopic quantum states in graphene are considered. In particular, we consider Rabi oscillations, rapid adiabatic passage for population transfer, and multiphoton excitation of the Fermi-Dirac sea in a monolayer graphene.
