Non-Hermitian skin effect induced by spatial noncommutativity
Zheng Wei, Su-Peng Kou
In all known schemes for the non-Hermitian skin effect, the non-Hermitian ingredient that drives the skin localization, whether asymmetric hopping or gain and loss, is invariably i…

Tuning Topological States by Dissipation
Xue-Ping Ren, Yue Hu, Long-Ye Lu +4
The bulk-boundary correspondence plays a crucial role in topological quantum systems, however,this principle is broken in non-Hermitian systems. The breakdown of the bulk-boundary…

Information Thermodynamics of Non-Hermitian Quantum Systems
Kui Cao, Qian Du, Su-Peng Kou
In this study, we uncover the intrinsic information processes in non-Hermitian quantum systems and their thermodynamic effects. We demonstrate that these systems can exhibit negati…
