Arbitrary Control of Non-Hermitian Skin Modes via Disorder and An Electric Field
Zhao-Fan Cai, Yang Li, Yu-Ran Zhang +4
The non-Hermitian skin effect (NHSE), characterized by the accumulation of a macroscopic number of bulk states at system boundaries, is a hallmark of non-Hermitian physics. However…
