Nonunitary Scaling Theory of Non-Hermitian Localization
Nonunitary Scaling Theory of Non-Hermitian Localization
Non-Hermiticity can destroy Anderson localization and lead to delocalization even in one dimension. However, the unified understanding of the non-Hermitian delocalization has yet to be established. Here, we develop a scaling theory of localization in non-Hermitian systems. We reveal that non-Hermiticity introduces a new scale and breaks down the one-parameter …
