Renormalization factor and effective mass of the two-dimensional electron gas
Markus Holzmann, Bernard Bernu, Valerio Olevano +2
We calculate the momentum distribution of the Fermi liquid phase of the homogeneous, two-dimensional electron gas. We show that, close to the Fermi surface, the momentum distributi…
Coherent electronic transport through graphene constrictions: sub-wavelength regime and optical analogies
Pierre Darancet, Valerio Olevano, Didier Mayou
Graphene two-dimensional nature combined with today lithography allows to achieve nanoelectronics devices smaller than the Dirac electrons wavelength. Here we show that in these gr…
Graphene nanodevices: bridging nanoelectronics and subwavelength optics
Pierre Darancet, Valerio Olevano, Didier Mayou
The unconventional properties of graphene, with a massless Dirac band dispersion and large coherence properties, have raised a large interest for applications in nanoelectronics. I…
Ab initio GW many-body effects in graphene
P. E. Trevisanutto, C. Giorgetti, L. Reining +2
We present an {\it ab initio} many-body GW calculation of the self-energy, the quasiparticle band plot and the spectral functions in free-standing undoped graphene. With respect to…
Linear plasmon dispersion in single-wall carbon nanotubes and the collective excitation spectrum of graphene
C. Kramberger, R. Hambach, C. Giorgetti +12
We have measured a strictly linear pi-plasmon dispersion along the axis of individualized single wall carbon nanotubes, which is completely different from plasmon dispersions of gr…
