Disorder and topology in planar arrays of resonant scatterers
Résumé
We study the impact of disorder- and topology-induced effects on light scattering in planar arrays of resonant scatterers (“atoms”). On the one hand, we show how the topological phenomena influence the strength of Anderson localization due to disorder. On the other hand, we explore the possibility of inducing nontrivial topological states by introducing disorder in an otherwise topologically trivial system. Our results demonstrate that studying topological properties provides an additional insight into wave physics of disordered systems.
