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…
