Emergence of Cascading Flat Bands in Breathing Superlattices
Moru Song, Jingyu Hu, Lina Shi +2
Flat bands have become a pillar of modern condensed matter physics and photonics owing to the vanishing group velocity and diverging density of states. Here, we present a paradigma…

Higher-order Skin Effect through a Hermitian-non-Hermitian Correspondence and Its Observation in an Acoustic Kagome Lattice
Jia-Xin Zhong, Pedro Fittipaldi de Castro, Tianhong Lu +8
The non-Hermitian skin effect (NHSE) is a distinctive topological phenomenon observed in nonHermitian systems. Recently, there has been considerable interest in exploring higher-or…
