摘要
We provide a description of the interaction between light and a three-dimensional electron gas in the framework of the Power-Zienau-Wooly (PZW) formulation of the quantum electrodynamics. The existence of the collective plasmon and plasmon-polariton modes of the gas appears as a consequence of the general properties of the PZW Hamiltonian. Our description enables a fully microscopic theory of the surface plasmon-polariton excitations, based on a quantum Hamiltonian that is free from any additional hypothesis regarding the material dispersion. This theory can therefore be applied to study the quantum optical properties of plasmon and surface plasmon waves.
