Finite-size energy gap in weak and strong topological insulators
Ken-Ichiro Imura, Mayuko Okamoto, Yukinori Yoshimura +2
The non-trivialness of a topological insulator (TI) is characterized either by a bulk topological invariant or by the existence of a protected metallic surface state. Yet, in reali…

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…
