Electronic Properties of Disordered Two-Dimensional Carbon
N. M. R. Peres, F. Guinea, A. H. Castro Neto
Two-dimensional carbon, or graphene, is a semi-metal that presents unusual low-energy electronic excitations described in terms of Dirac fermions. We analyze in a self-consistent w…
Entanglement and dephasing of quantum dissipative systems
T. Stauber, F. Guinea
The von Neumann entropy of various quantum dissipative models is calculated in order to discuss the entanglement properties of these systems. First, integrable quantum dissipative…
Interactions and disorder in 2D graphite sheets
Francisco Guinea, M. Pilar Lopez-Sancho, Maria A. H. Vozmediano
The present work discusses theoretical models which address the effects of electron--electron interactions and disorder in graphene planes. The starting point for the study is a si…
Coulomb Interactions and Ferromagnetism in Pure and Doped Graphene
N. M. R. Peres, F. Guinea, A. H. Castro Neto
We study the presence of ferromagnetism in the phase diagram of the two-dimensional honeycomb lattice close to half-filling (graphene) as a function of the strength of the Coulomb…
Many body effects in finite metallic carbon nanotubes
F. Guinea
The non homogeneity of the charge distribution in a carbon nanotube leads to the formation of an excitonic resonance, in a similar way to the one observed in X-ray absorption in me…
