Quasiclassical cyclotron resonance of Dirac fermions in highly doped graphene

Cyclotron resonance in highly doped graphene has been explored in the infrared magneto-transmission experiment. Contrary to previous works, which only focused on the magneto-optical properties of graphene in its quantum regime, here we study the quasi-classical response of this system. We show that it has a character of classical cyclotron resonance, which is linear in the applied magnetic field, with an effective cyclotron mass defined by the position of the Fermi level m = E_F/v_F^2.
