Plasmonic topological quasiparticle on the nanometre and femtosecond scales

Nature, Published online: 23 December 2020; doi:10.1038/s41586-020-3030-1

Topological plasmonic spin textures are excited by shining light on a structured silver film, and imaging defines how these quasiparticle field and spin textures evolve on the nanometre and femtosecond scales.
