The effects of retardation on the topological plasmonic chain: plasmonic edge states beyond the quasistatic limit

Simon R. Pocock, Paloma A. Huidobro, Vincenzo Giannini

We study a one-dimensional plasmonic system with non-trivial topology: a chain of metallic nanoparticles with alternating spacing, which is the plasmonic analogue to the Su-Schreif…
