Engineering Dirac electrons emergent on the surface of a topological insulator
Yukinori Yoshimura, Koji Kobayashi, Tomi Ohtsuki +1
The concept of topological insulator (TI) has introduced a new point of view to condensed-matter physics, relating a priori unrelated subfields such as quantum (spin, anomalous) Ha…
Manipulating quantum channels in weak topological insulator nanoarchitectures
Akihiko Matsumoto, Takashi Arita, Yositake Takane +2
In topological insulators protected surface states are always manifest, while in topological insulators (WTI) the corresponding metallic surface states are either m…
Dimensional crossover of transport characteristics in topological insulator nanofilms
Koji Kobayashi, Yukinori Yoshimura, Ken-Ichiro Imura +1
We show how the two-dimensional (2D) topological insulator evolves, by stacking, into a strong or weak topological insulator with different topological indices, proposing a new con…
Characterizing the weak topological properties: Berry phase point of view
Yukinori Yoshimura, Ken-Ichiro Imura, Takahiro Fukui +1
We propose classification schemes for characterizing two-dimensional topological phases with nontrivial weak indices. Here, "weak" implies that the Chern number in the correspondin…
