Gapless States Localized along a Staircase Edge in Second-Order Topological Insulators
Yuki Nagasato, Yositake Takane, Yukinori Yoshimura +2
A second-order topological insulator on a two-dimensional square lattice hosts zero-dimensional states inside a band gap. They are localized near and cor…

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…
