Helical Edge Modes near Transition to Topological Insulator with Indirect Gap
Shijun Mao, Yoshio Kuramoto
Helical edge modes are characteristic of topological insulators in two dimensions. This paper demonstrates that helical edge modes remain across transitions to ordinary insulators…

Analytic Theory of Edge Modes in Topological Insulators
Shijun Mao, Yoshio Kuramoto, Ken-Ichiro Imura +1
Spectrum and wave function of gapless edge modes are derived analytically for a tight-binding model of topological insulators on square lattice. Particular attention is paid to dep…

Zigzag edge modes in Z2 topological insulator: reentrance and completely flat spectrum
Ken-Ichiro Imura, Ai Yamakage, Shijun Mao +2
The spectrum and wave function of helical edge modes in Z_2 topological insulator are derived on a square lattice using Bernevig-Hughes-Zhang (BHZ) model. The BHZ model is characte…
