Comment on "Electron screening and excitonic condensation in double-layer graphene systems"
R. Bistritzer, H. Min, J. J. Su +1
The influence of screening on the condensed state of bilayer graphene is studied within the framework of the Thomas Fermi approximation. We find that screening has little effect on…
Quantum Wells in Polar-Nonpolar Oxide Heterojunction Systems
C. -C Joseph Wang, Bhagawan Sahu, Hongki Min +2
We address the electronic structure of quantum wells in polar-nonpolar oxide heterojunction systems focusing on the case of non-polar BaVO wells surrounded by polar LaTiO b…
Influence of Disorder on Electron-Hole Pair Condensation in Graphene Bilayers
R. Bistritzer, A. H. MacDonald
Graphene bilayers can condense into a state with spontaneous interlayer phase coherence that supports dissipationless counterflow supercurrents. Here we address the influence of di…
ARPES, Neutrons, and the High- Mechanism
Wei-Cheng Lee, A. H. MacDonald
Extensive ARPES and low-energy inelastic neutron scattering studies of cuprate superconductors can be successfully described using a weak-coupling theory in which quasiparticles on…
Density-Functional Theory of Graphene Sheets
Marco Polini, Andrea Tomadin, Reza Asgari +1
We outline a Kohn-Sham-Dirac density-functional-theory (DFT) scheme for graphene sheets that treats slowly-varying inhomogeneous external potentials and electron-electron interacti…
Intra-Landau level Cyclotron Resonance in Bilayer Graphene
Yafis Barlas, R. Cote, K. Nomura +1
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…
