Observation of non-Hermitian bulk-boundary correspondence in quantum dynamics
Lei Xiao, Tianshu Deng, Kunkun Wang +4
Bulk-boundary correspondence, a central principle in topological matter relating bulk topological invariants to edge states, breaks down in a generic class of non-Hermitian systems…

Topological quantum walks in momentum space with a Bose-Einstein condensate
Dizhou Xie, Tian-Shu Deng, Teng Xiao +4
We report the experimental implementation of discrete-time topological quantum walks of a Bose-Einstein condensate in momentum space. Introducing stroboscopic driving sequences to…

Non-Bloch topological invariants in a non-Hermitian domain-wall system
Tian-Shu Deng, Wei Yi
We study non-Bloch bulk-boundary correspondence in a non-Hermitian Su-Schieffer-Heeger model in a domain-wall configuration where the left and right bulks have different parameters…
