Geometric criterion of topological phase transition for non-Hermitian systems
Annan Fan, Shi-Dong Liang
We propose a geometric criterion of the topological phase transition for non-Hermitian systems. We define the length of the boundary of the bulk band in the complex energy plane fo…

Topological invariants of complex energy plane in non-Hermitian systems
Annan Fan, Shi-Dong Liang
Non-Hermitian systems as theoretical models of open or dissipative systems exhibit rich novel physical properties and fundamental issues in condensed matter physics.We propose a ge…
