Observation of flat-band skin effect
Xulong Wang, Dongyi Wang, Congwei Lu +4
Symmetry-protected ideal flat bands in one-dimensional (1D) Hermitian lattices are populated by compact localized states (CLS) - a special class of localization with wavefunctions…
Observation of the Exceptional Skin Effect on a Non-Hermitian Flat band
Dongyi Wang, Ruoyang Zhang, Chinghua Lee +2
Flat band and non-Hermitian are both significant conceptions in modern physics. In this study, we delve into the behaviours of flat bands in non-Hermitian systems, focusing on the…
Complex Frequency Fingerprint: Basic Concept and Theory
Juntao Huang, Kun Ding, Jiangping Hu +1
We introduce the complex frequency fingerprint (CFF), an experimentally accessible method for detecting the complex frequency Green's function (GF). Unlike the real frequency GF, w…
Quantum walks of correlated photons in non-Hermitian photonic lattices
Mingyuan Gao, Chong Sheng, Yule Zhao +6
Entanglement entropy characterizes the correlation of multi-particles and unveils the crucial features of open quantum systems. However, the experimental realization of exploring e…
