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…

Topological phases of many-body non-Hermitian systems
Kui Cao, Su-Peng Kou
We show that many-body fermionic non-Hermitian systems require two distinct sets of topological invariants to describe the topology of energy bands and quantum states respectively,…
