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…
