Parity and valley degeneracy in multilayer graphene
Mikito Koshino, Edward McCann
We study spatial symmetry in general ABA-stacked multilayer graphene to illustrate how electronic spectra at the two valleys are related in a magnetic field. We show that the latti…
Interlayer screening effect in graphene multilayers with ABA and ABC stacking
Mikito Koshino
We study the effect of perpendicular electric fields on the band structures of ABA and ABC graphene multilayers, and find that the electronic screening effect is significantly diff…
Trigonal warping and Berry's phase N pi in ABC-stacked multilayer graphene
Mikito Koshino, Edward McCann
The electronic band structure of ABC-stacked multilayer graphene is studied within an effective mass approximation. The electron and hole bands touching at zero energy support chir…
Magnetic field screening and mirroring in graphene
Mikito Koshino, Yasunori Arimura, Tsuneya Ando
The orbital magnetism in spatially varying magnetic fields is studied in monolayer graphene within the effective mass approximation. We find that, unlike the conventional two-dimen…
