Scale-Free Response with Directional Amplification in Critical Non-Hermitian Systems
Kunling Zhou, Zihe Yang, Bowen Zeng +1
The non-Hermitian skin effect can lead to directional amplification of response, with the associated end-to-end Green's function generally exhibiting size dependence. Any deviation…
Non-Hermitian Aharonov-Bohm Cage in Bosonic Bogoliubov-de Gennes Systems
Kunling Zhou, Bowen Zeng, Yong Hu
The non-Hermitian Aharonov-Bohm (AB) cage is a unique localization phenomenon that confines all possible excitations. This confinement leads to fully flat spectra in momentum space…
Inverse Design of Winding Tuple for Non-Hermitian Topological Edge Modes
Zihe Yang, Kunling Zhou, Bowen Zeng +1
The interplay between topological localization and non-Hermiticity localization in non-Hermitian crystal systems results in a diversity of shapes of topological edge modes (EMs), o…
Abnormal Frequency Response Determined by Saddle Points in Non-Hermitian Crystal Systems
Kunling Zhou, Jun Zhao, Bowen Zeng +1
In non-Hermitian crystal systems under open boundary condition (OBC), it is generally believed that the OBC modes with frequencies containing positive imaginary parts, when excited…
