Dirac-like Plasmons in Honeycomb Lattices of Metallic Nanoparticles
Dirac-like Plasmons in Honeycomb Lattices of Metallic Nanoparticles
We consider a two-dimensional honeycomb lattice of metallic nanoparticles, each supporting a localized surface plasmon, and study the quantum properties of the collective plasmons resulting from the near field dipolar interaction between the nanoparticles. We analytically investigate the dispersion, the effective Hamiltonian and the eigenstates of the collective plasmons for …
