Competition of non-Hermitian skin effect and topological localization of corner states observed in circuits
Chan Tang, Huanhuan Yang, Lingling Song +3
Exploring topological phases in non-Hermitian systems has attracted significant recent attention. One intriguing question is how topological edge states compete with the non-Hermit…
Observation of type-III corner states induced by long-range interactions
Huanhuan Yang, Lingling Song, Yunshan Cao +1
Long-range interactions (LRIs) are ubiquitous in nature. Higher-order topological (HOT) insulator represents a new phase of matter. A critical issue is how LRI dictates the HOT pha…
Square-root higher-order Weyl semimetals
Lingling Song, Huanhuan Yang, Yunshan Cao +1
The mathematical foundation of quantum mechanics is built on linear algebra, while the application of nonlinear operators can lead to outstanding discoveries under some circumstanc…
Experimental realization of two-dimensional weak topological insulators
Huanhuan Yang, Lingling Song, Yunshan Cao +1
We report the experimental realization of two-dimensional (2D) weak topological insulator (WTI) in spinless Su-Schrieffer-Heeger circuits with parity-time and chiral symmetries. St…
