Topological analysis of the quantum Hall effect in graphene: Dirac-Fermi transition across van Hove singularities and the edge vs bulk quantum numbers
Y. Hatsugai, T. Fukui, H. Aoki
Inspired by a recent discovery of a peculiar integer quantum Hall effect (QHE) in graphene, we study QHE on a honeycomb lattice in terms of the topological quantum number, with two…

Large orbital magnetic moments in carbon nanotubes generated by resonant transport
Naoto Tsuji, Shigehiro Takajo, Hideo Aoki
The nonequilibrium Green's function method is used to study the ballistic transport in metallic carbon nanotubes when a current is injected from the electrodes with finite bias vol…

Quantum Monte Carlo study for multiorbital systems with preserved spin and orbital rotational symmetries
Shiro Sakai, Ryotaro Arita, Karsten Held +1
We propose to combine the Trotter decomposition and a series expansion of the partition function for Hund's exchange coupling in a quantum Monte Carlo (QMC) algorithm for multiorbi…
