Polarization and plasmons in hot photoexcited graphene

Polarization and plasmons in hot photoexcited graphene
Ortwin Hess, Joachim M. Hamm, A. Freddie Page
We present a robust and exact method for calculating the polarization function and plasmon dispersion of graphene, for an arbitrary (isotropic) nonequilibrium carrier distribution, within the random phase approximation. This is demonstrated for a range of carrier distributions, including hot-carrier...
