Kohn Anomalies in Graphene Nanoribbons
Ken-ichi Sasaki, Masayuki Yamamoto, Shuichi Murakami +6
The quantum corrections to the energies of the point optical phonon modes (Kohn anomalies) in graphene nanoribbons are investigated. We show theoretically that the longitudinal…

Quantum spin Hall phases
Shuichi Murakami
We review our recent theoretical works on the the quantum spin Hall effect. First we compare edge states in various 2D systems, and see whether they are robust or fragile against p…
