The authors thank A V Malyshev for helpful comments.We study theoretically the level shift of massless Dirac fermions in a graphene monolayer subjected to a quantizing perpendicular magnetic field under the influence of short-range impurities. A Green function method is used to obtain closed expressions for the Landau level shift for any sharply peaked impurity potential approaching a delta-shell potential.engjournal articlehttp://dx.doi.org/10.1088/1751-8113/45/30/305002http://iopscience.iop.orgopen access538.9Dirac-equationPotentialsStatesFísica de materialesFísica del estado sólido2211 Física del Estado Sólido
