Localized states and skin effect around non-Hermitian impurities in tight-binding models

Balázs Hetényi, Balázs Dóra

We use the generalized Bloch theorem formalism of Alase {\it et al.} [{\it Phys. Rev. Lett.} {\bf 117} 076804 (2016)] to analyze simple one-dimensional tight-binding lattice system…
