Electron Condensation in a Jellium Coupled to a Finite Photonic Cavity

Unconventional properties of engineered Au–Ag nanostructures

“…Theoretical efforts to explain the unconventional response of these materials have increasingly emerged. Significant theoretical views include proposals regarding the role of strong correlations, exchange, as well as the advent of insulating character in these systems [19,[91][92][93].…”

“…More generally, the need for engineering softer plasmon modes in electron gases to enable high temperature plasmon mediated superconductivity is now widely recognized [16][17][18]. In this context, the possibility of reduced free electron density arising from electron localization in engineered metallic systems has also been proposed [19]. Further, coupled nanostructures (NSs) with localized surface plasmon resonances exhibit low energy modes due to plasmon hybridization.…”
