Polariton vs. Plasmon

Polaritonnoun

(physics) Any of a class of quasiparticles comprising elements of electromagnetic waves and excited states of matter.

Polariton

In physics, polaritons are quasiparticles resulting from strong coupling of electromagnetic waves with an electric or magnetic dipole-carrying excitation. They are an expression of the common quantum phenomenon known as level repulsion, also known as the avoided crossing principle.

Plasmonnoun

(genetics) All the genetic material in an organism.

Plasmonnoun

The quantum of waves produced by the collective effects of large numbers of electrons when disturbed from equilibrium.

Plasmonnoun

A flourlike food preparation made from skim milk, and consisting essentially of the unaltered proteid of milk. It is also used in making biscuits and crackers, for mixing with cocoa, etc. A mixture of this with butter, water, and salt is called Plasmon butter, and resembles clotted cream in appearance.

Plasmon

In physics, a plasmon is a quantum of plasma oscillation. Just as light (an optical oscillation) consists of photons, the plasma oscillation consists of plasmons.
