Spontaneously formed excitonic density wave with vortex-antivortex lattice in twisted semiconductor bilayers
Deguang Wu, Yiran Xue, Baigeng Wang +2
Exciton condensation, characterized by uniform phase coherence across macroscopic length scales, has enabled the discovery of a variety of excitonic states, greatly enriching our u…
Spectral Visualization of Excitonic Pair Breaking at Individual Impurities in Ta2Pd3Te5
Lianzhi Yang, Deguang Wu, Hanbo Zhang +9
Excitonic insulators host the condensates of bound electron-hole pairs, offering a platform for studying correlated bosonic quantum states. Yet, how macroscopic coherence emerges f…
Effective impurity behavior emergent from non-Hermitian proximity effect
Deguang Wu, Jiasong Chen, Wei Su +3
Non-Hermitian boundaries commonly take place in many open quantum systems locally coupled to a surrounding environment. Here, we reveal a type of non-Hermitian effect induced by no…
Connections between the Open-boundary Spectrum and Generalized Brillouin Zone in Non-Hermitian Systems
Deguang Wu, Jiao Xie, Yao Zhou +1
Periodic-boundary spectrum, open-boundary spectrum, as well as the generalized Brillouin zone (GBZ) are three essential properties of a one-dimensional non-Hermitian system. In thi…
