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…

Spherical topological insulator
Ken-Ichiro Imura, Yukinori Yoshimura, Yositake Takane +1
The electronic spectrum on the spherical surface of a topological insulator reflects an active property of the helical surface state that stems from a constraint on its spin on a c…
