In physics, a plasmon is a quantum of plasma oscillation. The plasmon is a quasiparticle resulting from the quantization of plasma oscillations just as photons and phonons are quantizations of light and mechanical vibrations, respectively (though the photon is an elementary particle, not a quasiparticle). Thus, plasmons are collective oscillations of the free electron gas density, for example, at optical frequencies. Plasmons can couple with a photon to create another quasiparticle called a plasma polariton.
Since plasmons are the quantization of classical plasma oscillations, most of their properties can be derived directly from Maxwell's equations.
