Nonclassical effects in plasmonics: An energy perspective to quantify nonclassical effects
Nonclassical effects in plasmonics: An energy perspective to quantify nonclassical effects
Plasmons are commonly interpreted with classical electrodynamics, while nonclassical effects may influence the dynamics of plasmon resonances as the plasmon confinement is approaching the few--nanometer scale. However, an unambiguous approach to quantify the degree of nonclassical dynamics remains. We propose a nonclassical-impact parameter (NCI) to characterize the degree of nonclassical …
