Higher-order topological insulators and semimetals in generalized Aubry-André-Harper models
Qi-Bo Zeng, Yan-Bin Yang, Yong Xu
Higher-order topological phases of matter have been extensively studied in various areas of physics. While the Aubry-André-Harper model provides a paradigmatic example to study top…

Topological Phases in Non-Hermitian Aubry-André-Harper Models
Qi-Bo Zeng, Yan-Bin Yang, Yong Xu
Topological phases have recently witnessed a rapid progress in non-Hermitian systems. Here we study a one-dimensional non-Hermitian Aubry-André-Harper model with imaginary periodic…
