Microscopic quantum description of surface plasmon polaritons: Revealing intrinsic ultrastrong light-matter coupling
Florian Maurer, Thomas F. Allard, Yanko Todorov +2
We develop a microscopic quantum theory of surface plasmon polaritons valid for arbitrary metal-dielectric geometries. Our framework is based on the Power-Zienau-Woolley representa…

Quantum theory of plasmon polaritons in chains of metallic nanoparticles: From near- to far-field coupling regime
Thomas F. Allard, Guillaume Weick
We develop a quantum theory of plasmon polaritons in chains of metallic nanoparticles, describing both near- and far-field interparticle distances, by including plasmon-photon Umkl…
