VOLUME 91 | ISSUE 6 | PAGE 334 Energy gaps at neutrality point in bilayer graphene in a magnetic field E. V. Gorbar, V. P. Gusynin, V. A. Miransky* Bogolyubov Institute for Theoretical Physics, 03680 Kiev, Ukraine *Department of Applied Mathematics, University of Western Ontario, London, N6A 5B7 Ontario, Canada Abstract Utilizing the Baym-Kadanoff formalism with the polarization function calculated in the random phase approximation, the dynamics of the ν=0 quantum Hall state in bilayer graphene is analyzed. Two phases with nonzero energy gap, the ferromagnetic and layer asymmetric ones, are found. The phase diagram in the plane , where is a top-bottom gates voltage imbalance, is described. It is shown that the energy gap scales linearly, , with magnetic field. Download PS file (GZipped, 237.5K)  |  Download PDF file (270.1K) Список работ, цитирующих данную статью, см. здесь.
