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…

Three-dimensional Meta-atoms for High Confinement of Mid-IR Radiation
Francesco Pisani, Usama Iqbal, Laure Tailpied +3
The ability to confine photons into structures with highly sub-wavelength volumes is extremely interesting for many applications such as sensing, nonlinear optics, and strong light…
