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…

Renormalization group approach to anisotropic superconductivity
Rafael Roldan, Shan-Wen Tsai, M. Pilar Lopez-Sancho
The superconducting instability of the Fermi liquid state is investigated by considering anisotropic electron-boson couplings. Both electron-electron interactions and anisotropic e…
