Superradiance—a cooperative phenomenon originally predicted by Dicke in 1954 for two-level atoms—consists of ubiquitous collective dynamics. Such an effect has been observed in a huge number of systems, both quantum and classical. Despite a large body of theoretical...

A spaser is a nanoplasmonic counterpart of a laser, with photons replaced by surface plasmon polaritons and a resonant cavity replaced by a metallic nanostructure supporting localized plasmonic modes. By combining analytical results and first‐principle numerical...
