Robust zero modes in non-Hermitian systems without global symmetries
Jose D. H. Rivero, Courtney Fleming, Bingkun Qi +2
We present an approach to achieve zero modes in lattice models that do not rely on any symmetry or topology of the bulk, which are robust against disorder in the bulk of any type a…

Defect states emerging from a non-Hermitian flat band of photonic zero modes
Bingkun Qi, Lingxuan Zhang, Li Ge
We show the existence of a flat band consisting of photonic zero modes in a gain and loss modulated lattice system, as a result of the underlying non-Hermitian particle-hole symmet…
