Excitonic Effects on the Optical Response of Graphene and Bilayer Graphene
Li Yang, Jack Deslippe, Cheol-Hwan Park +2
We present first-principles calculations of many-electron effects on the optical response of graphene, bilayer graphene, and graphite employing the GW-Bethe Salpeter equation appro…

First-Principles Study of Electron Linewidths in Graphene
Cheol-Hwan Park, Feliciano Giustino, Catalin D. Spataru +2
We present first-principles calculations of the linewidths of low-energy quasiparticles in n-doped graphene arising from both the electron-electron and the electron-phonon interact…
