TL;DR: The findings show that deep subwavelength mode volumes V together with quality factors Q that are reasonably high for plasmonic nanostructures result in a strong-coupling figure of merit-Q/sqrt[V] as high as ∼6×10^{3} μm^{-3/2], a value comparable to state-of-the-art photonic crystal and microring resonator cavities, which suggests that plas mon

TL;DR: In this paper, the authors present general theoretical formalism describing strong coupling and give an overview of various photonic structures and materials allowing for realization of this regime, including plasmonic and dielectric nanoantennas, novel two-dimensional materials, carbon nanotubes, and molecular vibrational transitions.

TL;DR: This work reports on strong interaction between localized surface plasmons in silver nanoprisms and excitons and trions in monolayer tungsten disulfide (WS2) and shows that the plasmon-exciton interactions can be efficiently tuned by controlling the charged versus neutral exciton contribution to the coupling process.

TL;DR: It is shown that a nanoscale system, composed of a plasmonic nanoprism strongly coupled to excitons in a J-aggregated form of organic chromophores, experiences modified excited-state dynamics and, therefore, modified photochemical reactivity.

TL;DR: In this paper, the authors demonstrate mode splitting not only in scattering, but also in photoluminescence of individual hybrid nanosystems, which manifests a direct proof of strong coupling in plasmon-exciton nanoparticles.
