Abstract
Characteristics of two forms of the electron-hole (eh) plasma radiation, excited in the graphene under the action of an external time dependent electric
field, namely, the quasiclassical radiation of plasma waves and the quantum photon emission in the annihilation channel of interaction of the eh-plasma with a
quantized electromagnetic field, are investigated and compared among themselves by analytical and numerical methods. The analysis is based on a consequent kinetic theory where the excitation of the eh-plasma by an external field
is described nonperturbatively, while the interaction with a quantized field
is taken into account in the second order of perturbation theory. It is showed
that the peculiarities of two types of radiation (spectrum, radiation patterns)
are accessible for experimental verification. The obtained results are compared
also with a direct analysis of the photon emission in the graphene, based on
an exact solution of a Dirac-like equation of motion of carriers in an external
electric pulse, and also with the experimental data.
