Stimulated by experimental work in the possibility of preserving nonclassical correlations in light-matter interactions mediated by scattering of photons and plasmons, it has been assumed that similar dynamics underlie the conservation of the quantum fluctuations that define the nature of light sources. An international team of researchers (Usa – State University of Louisiana, University of Alabama, Mexico) demonstrated that the quantum statistics of multiparticle systems are not always preserved in plasmonic platforms and report the observation of their modification. They showed that optical near fields provide additional scattering paths that can induce complex multiparticle interactions. The resulting multiparticle dynamics can lead to the modification of the excitation mode of plasmonic systems. The observations were validated through the quantum theory of optical coherence for single- and multi-mode plasmonic systems. The possibility of using nanoscale system to create exotic forms of light could pave the way for next-generation quantum devices. It could also constitute a novel platform for exploring novel quantum phenomena…read more. Open Access TECHNICAL ARTICLE
