# Intra-Landau-Level Cyclotron Resonance in Bilayer Graphene

 Title Intra-Landau-Level Cyclotron Resonance in Bilayer Graphene Publication Type Journal Article Year of Publication 2008 Authors Barlas, Y, Côté, R, Nomura, K, MacDonald, AH Journal Physical Review Letters Volume 101 Pagination 097601 Abstract Interaction driven integer quantum-Hall effects are anticipated in graphene bilayers because of the near degeneracy of the eight Landau levels which appear near the neutral system Fermi level. We predict that an intra-Landau-level cyclotron resonance signal will appear at some odd-integer filling factors, accompanied by collective modes which are nearly gapless and have approximate k3/2 dispersion. We speculate on the possibility of unusual localization physics associated with these modes. URL http://link.aps.org/abstract/PRL/v101/e097601 Full Text
