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.…
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…
Non-equlibrium effects in transport through quantum dots
E. Bascones, C. P. Herrero, F. Guinea +1
The role of non-equilibrium effects in the conductance through quantum dots is investigated. Associated with single-electron tunneling are shake-up processes and the formation of e…
