  • Drude weight, plasmon dispersion, and a.c. conductivity in doped graphene sheets 

    Abedinpour, Saeed H.; Vignale, Giovanni, 1957-; Principi, A.; Polini, Marco; Tse, Wang-Kong; MacDonald, A. H. (arXiv, 2011)
    We demonstrate that the plasmon frequency and Drude weight of the electron liquid in a doped graphene sheet are strongly renormalized by electron-electron interactions even in the long-wavelength limit. This e ffect is not ...
