Non-Hermitian impurities in Dirac systems

Year: 2020

Type: article

Abstract: The non-Hermitian impurity resonance in Dirac systems is predicted. Depending on the impurity strength, the resonance can be manifested as a trigonal profile of the local density of states or even as a peak at the impurity site. This finding paves the way for the exploration of the non-Hermitian effects in systems with defects.
