Recurrence method in Non-Hermitian Systems
Haoyan Chen, Yi Zhang
We propose a novel and systematic recurrence method for the energy spectra of non-Hermitian systems under open boundary conditions based on the recurrence relations of their charac…

Understanding Fermionic Generalized Symmetries
Federico Ambrosino, Ran Luo, Yi-Nan Wang +1
We explore new aspects of internal fermionic shifting symmetries, present in physical systems such as free Dirac spinors and p-form tensor-spinor fields. We propose a novel procedu…

Braiding Topology of Non-Hermitian Open-Boundary Bands
Yongxu Fu, Yi Zhang
There has been much recent interest and progress on topological structures of the non-Hermitian Bloch bands. Here, we study the topological structures of non-Bloch bands of non-Her…
