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…

Real spectra in one-dimensional single-band non-Hermitian Hamiltonians
Haoyan Chen, Yi Zhang
In general, the energy spectrum of a non-Hermitian system turns out to be complex, which is not so satisfactory since the time evolution of eigenstates with complex eigenvalues is…
