Topological photonics (2018, background): “Finally, two-dimensional topological edge state lasers (Bahari et al., 2017; Bandres et al., 2018; Harari et al., 2018), intrinsically non-Hermitian systems, have been observed recently; thus, it will become increasingly necessary to put on firm ground the complex interplay of non-Hermiticity and…”
