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…
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…
Type-II Weyl Excitation in Vortex Arrays
Z. -X. Li, X. S. Wang, Lingling Song +2
Weyl-like magnon excitations in ordered magnets have attracted significant recent attention. Despite of the tantalizing physics and application prospects, the experimental observat…
Experimental observation of edge-dependent quantum pseudospin Hall effect
Huanhuan Yang, Lingling Song, Yunshan Cao +2
It is a conventional wisdom that the helical edge states of quantum spin Hall (QSH) insulator are particularly stable due to the topological protection of time-reversal symmetry. H…
Realization of the square-root higher-order topological insulator in electric circuits
Lingling Song, Huanhuan Yang, Yunshan Cao +1
Higher-order topological insulator (HOTI) represents a new phase of matter, the characterization of which goes beyond the conventional bulk-boundary correspondence and is attractin…
