Algebraic States in Continuum in Dimensional Non-Hermitian Systems
Ao Yang, Kai Zhang, Chen Fang
We report the existence of algebraically localized eigenstates embedded within the continuum spectrum of 2D non-Hermitian systems with a single impurity. These modes, which we term…

Tailoring Bound State Geometry in High-Dimensional Non-Hermitian Systems
Ao Yang, Zixi Fang, Kai Zhang +1
It is generally believed that the non-Hermitian effect (NHSE), due to its non-reciprocal nature, creates barriers for the appearance of impurity bound states. In this paper, we fin…
