However, different types of non-Hermiticity have been barely studied and their characteristics remain elusive.
In this work, we focus on a non-Hermitian system where the hopping phase exists non-reciprocally and discuss the evolution of localization characteristics of the quantum states. We emphasize that the non-Hermiticity encoded in the hopping phase factor suppresses localization of the states in contrast to the non-Hermitian skin effect.
Furthermore, by quantifying the localization in the spectrum considering the inverse participation ratio and fractal dimension, we demonstrate that the non-Hermitian phase factor in the hopping terms controls the localization characteristics of the quantum states emergent in the quasicrystal. Our works offer the new types of non-Hermitian systems which are able to control of wave localization with various applications.
