Effect of electron-electron interaction on the Fermi surface topology of doped graphene
R. Roldan, M. P. Lopez-Sancho, F. Guinea
The electron-electron interactions effects on the shape of the Fermi surface of doped graphene are investigated. The actual discrete nature of the lattice is fully taken into accou…

Self-energy corrections to anisotropic Fermi surfaces
R. Roldan, M. P. Lopez-Sancho, F. Guinea +1
The electron-electron interactions affect the low-energy excitations of an electronic system and induce deformations of the Fermi surface. These effects are especially important in…

Many body effects on - axis properties: out of plane coherence and bilayer splitting
F. Guinea, M. P. Lopez-Sancho, M. A. H. Vozmediano
The out-of-plane hopping in layered metals with strong electronic correlation is analyzed theoretically. By studying the effects of in-plane interactions on the interlayer tunnelli…
