Critical Non-Hermitian Edge Modes
Kunling Zhou, Zihe Yang, Bowen Zeng +1
We unveil a unique critical phenomenon of topological edge modes in non-Hermitian systems, dubbed the critical non-Hermitian edge modes (CNHEM). Specifically, in the thermodynamic…

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…
