Robust zero-energy states in two-dimensional Su-Schrieffer-Heeger topological insulators
Zhang-Zhao Yang, An-Yang Guan, Wen-Jie Yang +2
The Su-Schrieffer-Heeger (SSH) model on a two-dimensional square lattice has been considered as a significant platform for studying topological multipole insulators. However, due t…
A General Method to Design Acoustic Higher-Order Topological Insulators
An-Yang Guan, Zhang-Zhao Yang, Xin-Ye Zou +1
Acoustic systems that are without limitations imposed by the Fermi level have been demonstrated as significant platform for the exploration of fruitful topological phases. By surro…
Topological Classical Systems with Generalized Chiral Symmetry
Zhang-Zhao Yang, An-Yang Guan, Xin-Ye Zou +1
The bulk band topology of symmetry invariant adiabatic systems in the thermodynamic limit are considered to be determined by the hopping energy. In this work, we present that in cl…
