Polarization and plasmons in hot photoexcited graphene
A. Freddie Page, Joachim M. Hamm, Ortwin Hess
We present a robust and exact method for calculating the polarization function and plasmon dispersion of graphene, for an arbitrary (isotropic) non-equilibrium carrier distribution…
Nonequilibrium plasmon emission drives ultrafast carrier relaxation dynamics in photoexcited graphene
J. M. Hamm, A. F. Page, J. Bravo-Abad +2
The fast decay of carrier inversion in photoexcited graphene has been attributed to optical phonon emission and Auger recombination. Plasmon emission provides another pathway that,…
Nonequilibrium plasmons with gain in graphene
A. Freddie Page, Fouad Ballout, Ortwin Hess +1
Graphene supports strongly confined transverse-magnetic sheet plasmons whose spectral characteristics depend on the energetic distribution of Dirac particles. The question arises w…
