赝拓扑绝缘体

Pseudo topological insulators

C. Yuce

摘要:

我们预测了以前被忽视的伪拓扑绝缘体。我们确定了一些条件下,强大的伪拓扑边状态出现,并说明我们的想法与额外的手征对称性破缺势的Su-Schrieffer-Heeger(SSH)模型。讨论了在带隙不闭合的情况下发生的赝拓扑绝缘相变。

英文摘要:

We predict pseudo topological insulators that have been previously overlooked. We determine some conditions under which robust pseudo topological edge states appear and illustrate our idea on the Su-Schrieffer-Heeger (SSH) model with extra chiral symmetry breaking potentials. We discuss that pseudo topological insulating phase transition occurs without band gap closing.
