Universal Generalized Brillouin Zone Theory I: Review of the Spectral Approach
Zeqi xu, Jiangping Hu, Zhesen Yang
This series of papers aims to establish a universal generalized Brillouin zone (GBZ) theory for higher-dimensional non-Hermitian systems. As the starting point of this series, we e…

Non-Hermitian Quantum Mechanics I: Instantaneous Self-Energy
Lingfeng Liu, Wei-Wei Yang, Jiangping Hu +1
Starting from the unitary evolution of a closed quantum system, we rigorously demonstrate that the projection of the global wavefunction onto an arbitrary local subsystem is govern…

Dynamical Degeneracy Splitting and Directional Invisibility in Non-Hermitian Systems
Kai Zhang, Chen Fang, Zhesen Yang
In this paper, we introduce the concept of dynamical degeneracy splitting to describe the anisotropic decay behaviors in non-Hermitian systems. We demonstrate that systems with dyn…
