Unconventional quasiparticle lifetime in graphite
J. Gonzalez, F. Guinea, M. A. H. Vozmediano
The influence of electron-electron scattering on quasiparticle lifetimes in graphite is calculated. In the limit when the Fermi surface is reduced to isolated points in the Brillou…
Renormalization Group Approach to the Normal State of Copper-Oxide Superconductors
J. Gonzalez, F. Guinea, M. A. H. Vozmediano
We study by means of renormalization group techniques the effect that on the two-dimensional electron liquid may have the van Hove singularities observed experimentally in the copp…
Renormalization group analysis of electrons near a Van Hove singularity.
J. Gonzalez, F. Guinea, M. A. H. Vozmediano
A model of interacting two dimensional electrons near a Van Hove singularity is studied, using renormalization group techniques. In hole doped systems, the chemical potential is fo…
Shake-up effects and intermolecular tunneling in C ions
F. Guinea, J. Gonzalez, M. A. H. Vozmediano
The multiplet structure induced by the Coulomb interactions in C () is analyzed. The partially ocuppied LUMO gives rise to a set of levels which fill a rela…
Electrostatic screening in fullerene molecules
J. Gonzalez, F. Guinea, M. A. H. Vozmediano
The screening properties of fullerene molecules are described by means of a continuum model which uses the electronic wavefunctions of planar graphite as a starting point. The long…
The Electronic Spectrum of Fullerenes from the Dirac Equation
J. González, F. Guinea, M. A. H. Vozmediano
The electronic spectrum of sheets of graphite (plane honeycomb lattice) folded into regular polihedra is studied. A continuum limit valid for sufficiently large molecules and based…
