Localization Transition in Incommensurate non-Hermitian Systems

Amin Jazaeri, Indubala I. Satija

A class of one-dimensional lattice models with incommensurate complex potential $V(\theta )=2[{\lambda }_{r}cos(\theta )+i{\lambda }_{i}sin(\theta )]$ is found to exhibit localization transition at $|{\lambda }_r|+|{\lambda }_i|=1$. Th…
