Open-system analogy of Berry conjecture
Yaohua Li, Yunhan Wang, Yong-Chun Liu
Berry conjecture is central to understanding quantum chaos in isolated systems and foundational for the eigenstate thermalization hypothesis. Here we establish an open-system analo…

General theory for geometry-dependent non-Hermitian bands
Chenyang Wang, Jinghui Pi, Qinxin Liu +2
In two- and higher-dimensional non-Hermitian lattices, systems can exhibit geometry-dependent bands, where the spectrum and eigenstates under open boundary conditions depend on the…
