Description
In this paper, we study numerical solutions of a system of quantum kinetic equations and Maxwell's equations that describe: (a) the production (in terms of Schwinger effect) and dynamics of charge carriers in a graphene monolayer under the action of a classical spatially homogeneous time-dependent electromagnetic field of linear polarization; (b) classical radiation caused by electric currents; (c) quantum radiation caused by the recombination of electrons and holes, as well as by their scattering. The quantities (quasiparticle number density, current density, radiation intensity and spectrum, absorption, reflection and transmission coefficients in a graphene monolayer) are calculated as functions of time and/or as functions of parameters of the external field, that is the amplitude and duration of electric field. Our results, obtained within the framework of the quantum kinetic equations, are compared with theoretical and experimental results of other research groups.
