Abstract: A27.00005 : Electron-electron interactions in doped graphene sheets*
10:24 AM–11:00 AM
(NEST, Istituto Nanoscienze-CNR)
In this talk I will review some of the most important electronic properties of graphene. I will first discuss the appearance of plasmaron satellite bands in both angle-resolved photoemission  and STM spectra [2,3], emphasizing the important role of the sublattice pseudospin degree of freedom. I will then illustrate some unusual features, which appear only beyond the widely used Random Phase Approximation, characterizing plasmons and Drude weight of the electron gas in this material~.\\[4pt]  A.
