Effect of Coulomb interactions on the physical observables of graphene
Maria A. H. Vozmediano, Francisco Guinea
We give an update of the situation concerning the effect of electron-electron interactions on the physics of a neutral graphene system at low energies. We revise old renormalizatio…
Electron-induced rippling in graphene
P. San-Jose, J. Gonzalez, F. Guinea
We show that the interaction between flexural phonons, when corrected by the exchange of electron-hole excitations, may place the graphene sheet very close to a quantum critical po…
Local defects and ferromagnetism in graphene layers
M. A. H. Vozmediano, M. P. Lopez-Sancho, T. Stauber +1
We study the changes in the electronic structure induced by lattice defects in graphene planes. In many cases, lattice distortions give rise to localized states at the Fermi level.…
Disorder and interaction effects in two dimensional graphene sheets
T. Stauber, F. Guinea, M. A. H. Vozmediano
The interplay between different types of disorder and electron-electron interactions in graphene planes is studied by means of Renormalization Group techniques. The low temperature…
Properties of electrons near a Van Hove singularity
M. A. H. Vozmediano, J. Gonzalez, F. Guinea +2
The Fermi surface of most hole-doped cuprates is close to a Van Hove singularity at the M point. A two-dimensional electronic system, whose Fermi surface is close to a Van Hove sin…
Aharonov-Bohm oscillations of a particle coupled to dissipative environments
F. Guinea
The amplitude of the Bohm-Aharonov oscillations of a particle moving around a ring threaded by a magnetic flux and coupled to different dissipative environments is studied. The dec…
