Graphene wormholes: A condensed matter illustration of Dirac fermions in curved space
J. Gonzalez, J. Herrero
We study the properties of graphene wormholes in which a short nanotube acts as a bridge between two graphene sheets, where the honeycomb carbon lattice is curved from the presence…
Kohn-Luttinger superconductivity in graphene
J. Gonzalez
We investigate the development of superconductivity in graphene when the Fermi level becomes close to one of the Van Hove singularities of the electron system. The origin of the pa…
Unconventional quasiparticle lifetime in undoped graphene
J. Gonzalez, E. Perfetto
We address the question of how small can the quasiparticle decay rate be at low energies in undoped graphene, where kinematical constraints are known to prevent the decay into part…
Quantum Hall effect in carbon nanotubes and curved graphene strips
E. Perfetto, J. Gonzalez, F. Guinea +2
We develop a long wavelength approximation in order to describe the low-energy states of carbon nanotubes in a transverse magnetic field. We show that, in the limit where the squar…
Electronic instabilities of a Hubbard model approached as a large array of coupled chains: competition between d-wave superconductivity and pseudogap phase
E. Perfetto, J. Gonzalez
We study the electronic instabilities in a 2D Hubbard model where one of the dimensions has a finite width, so that it can be considered as a large array of coupled chains. The fin…
Cooper-pair propagation and superconducting correlations in graphene
J. Gonzalez, E. Perfetto
We investigate the Cooper-pair propagation and the proximity effect in graphene under conditions in which the distance L between superconducting electrodes is much larger than the…
