摘要：

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. We find that the electronic fluid can be described by a non-interacting-like dispersion but with renormalized parameters. We compare our results with recent cyclotron resonance experiments in this system. Copyright (C) EPLA, 2009
