On the Spectrum of a Discrete Non-Hermitian Quantum System
Ebru Ergun Department of Physics, Ankara University, 06100 Tandogan, Ankara, Turkey
Abstract:
In this paper, we develop spectral analysis of a discrete non-Hermitian quantum system that is a discrete counterpart of some continuous quantum systems on a complex contour. In particular, simple conditions for
discreteness of the spectrum are established.
Keywords:
difference operator; non-Hermiticity; spectrum; eigenvalue; eigenvector; completely continuous operator.
