In this talk, I will discuss some of my recent work in topological
nanophotonics, a growing field which seeks to exploit ideas from geometry and
topology in order to control light at the nanoscale. In particular, I will
introduce a model of topological plasmons in a chain of metallic
nanoparticles, and I will discuss the interplay between the topological nature
of the collective excitations and various effects, including: long-range
interactions, collective Lamb shifts, and strong light-matter coupling in a
cavity. Our model has implications for important concepts in topological
matter, including the celebrated bulk-edge correspondence.
