Topological edge and corner states in coupled wave lattices in nonlinear polariton condensates
Topological edge and corner states in coupled wave lattices in nonlinear polariton condensates
Abstract Topological states have been widely investigated in different types of systems and lattices. In the present work, we report on topological edge states in double-wave (DW) chains, which can be described by a generalized Aubry-André-Harper (AAH) model. For the specific system of a driven-dissipative exciton polariton system we show …
