Flat bands in lattices with non-Hermitian coupling

Flat bands in lattices with non-Hermitian coupling

We study non-Hermitian photonic lattices that exhibit competition between conservative and non-Hermitian (gain/loss) couplings. A bipartite sublattice symmetry enforces the existence of non-Hermitian flat bands, which are typically embedded in an auxiliary dispersive band and give rise to nondiffrac...
