Brillouin-Wigner theory for high-frequency expansion in periodically driven systems: Application to Floquet topological insulators
Takahiro Mikami, Sota Kitamura, Kenji Yasuda +3
We construct a systematic high-frequency expansion for periodically driven quantum systems based on the Brillouin-Wigner (BW) perturbation theory, which generates an effective Hami…
Electronic structure of helicoidal graphene: massless Dirac particles on a curved surface with a screw symmetry
Masataka Watanabe, Hisato Komatsu, Naoto Tsuji +1
Massless Dirac particles on the helicoid are theoretically investigated. With its possible application being helical graphene, we explore how the peculiarities of Dirac particles a…
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…
