Quasiparticle carrier dynamics in graphene from first principles

ORAL

Abstract

It is important to understand how a charge carrier in real materials interacts with other charge carriers or with the lattice vibration; these two effects, electron-electron interactions and electron-phonon interactions, respectively, largely determine the quasiparticle and transport properties of a material. In this presentation, we will show that some aspects of quasiparticle dynamics in graphene can be described by first-principles calculations considering these two effects.
