Hot carrier dynamics and electron-optical phonon coupling in photoexcited graphene via time-resolved ultrabroadband terahertz spectroscopy
Sho Ikeda, Chiko Otani, Masatsugu Yamashita
Electron-electron (e-e) interaction is known as a source of logarithmic renormalizations for Dirac fermions in quantum field theory. The renormalization of electron--optical phonon…

Intrinsic and extrinsic effects on intraband optical conductivity of hot carriers in photoexcited graphene
Masatsugu Yamashita, Chiko Otani
We present a numerical study on the intraband optical conductivity of hot carriers at quasi-equilibria in photoexcited graphene based on the semiclassical Boltzmann transport equat…
