Topological Word for Non-Abelian Topological Insulators
Zhenming Zhang, Tianyu Li, Wei Yi
We propose a unified framework, dubbed topological word, for the complete non-Abelian bulk-boundary correspondence in multigap non-Abelian topological insulators. Composed by an or…

Biorthogonal topological charge pumping in non-Hermitian systems
Zhenming Zhang, Tianyu Li, Xiwang Luo +1
We study charge pumping in generic non-Hermitian settings and show that quantized charge pumping is only guaranteed under a biorthogonal formalism therein, where the charge transpo…
