Journal ArticleDOI
Dynamical polarizability of graphene beyond the Dirac cone approximation
TL;DR: In this article, the authors compute the dynamical polarizability of graphene beyond the usual Dirac cone approximation, integrating over the full Brillouin zone, and derive an approximate analytical expression.
Journal ArticleDOI
Quasi-Flat Plasmonic Bands in Twisted Bilayer Graphene
TL;DR: The charge susceptibility of twisted bilayer graphene is investigated in the Dirac cone and it is argued that collective excitonic modes that exist in the undoped material with an almost constant energy dispersion arise from the interaction of quasi-localized states with the incident light field.
Journal ArticleDOI
Interacting Electrons in Graphene: Fermi Velocity Renormalization and Optical Response.
TL;DR: A Hartree-Fock theory for electrons on a honeycomb lattice aiming to solve a long-standing problem of the Fermi velocity renormalization in graphene is developed and an explicit expression for the optical conductivity is derived via precise quantum Monte Carlo calculations which compares well to the mean-field approach.
Journal ArticleDOI
Electron-electron interactions and charging effects in graphene quantum dots
TL;DR: In this paper, the authors analyzed charging effects in graphene quantum dots and showed that when the Fermi level is far from the neutrality point, charging effects lead to a shift in the electrostatic potential and the dot shows standard Coulomb blockade features.
Journal ArticleDOI
Effect of Holstein phonons on the electronic properties of graphene
TL;DR: In this article, the self-energy of the electronic propagator due to the presence of Holstein polarons was obtained within the first Born approximation, which leads to a renormalization of the Fermi velocity of 1%.
