Non-Hermitian impurities in Dirac systems
P. O. Sukhachov, A. V. Balatsky
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.
