Topological insulator states in quasi-one-dimensional sawtooth chain
Zhihao Xu, Linhu Li
We report the discovery of flatten Bloch bands with nontrivial topological numbers in a quasi-one-dimensional sawtooth chain. We present the nearly flat-band with a obvious gap and…

Topological phases of generalized Su-Schrieffer-Heeger models
Linhu Li, Zhihao Xu, Shu Chen
We study the extended Su-Schrieffer-Heeger model with both the nearest-neighbor and next-nearest-neighbor hopping strengths being cyclically modulated and find the family of the mo…
