Electron-electron interactions in graphene bilayers
S. Viola Kusminskiy, D. K. Campbell, A. H. Castro Neto
We study the effect of electron-electron interactions in the quasiparticle dispersion of a graphene bilayer within the Hartree-Fock-Thomas-Fermi theory by using a four-bands model.…
Electronic compressibility of a graphene bilayer
S. Viola Kusminskiy, Johan Nilsson, D. K. Campbell +1
We calculate the electronic compressibility arising from electron-electron interactions for a graphene bilayer within the Hartree-Fock approximation. We show that, due to the chira…
Quantum Magnetic Impurities in Magnetically Ordered Systems
A. H. Castro Neto, E. Novais, L. Borda +2
We discuss the problem of a spin 1/2 impurity immersed in a spin S magnetically ordered background. We show that the problem maps onto a generalization of the dissipative two level…
