    Any of a class of quasiparticles comprising elements of electromagnetic waves and excited states of matter

Wikipedia

  1. Polariton

    ‹See Tfd› 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. Polaritons describe the crossing of the dispersion of light with any interacting resonance. To this extent polaritons can also be thought of as the new normal modes of a given material or structure arising from the strong coupling of the bare modes, which are the photon and the dipolar oscillation. The polariton is a bosonic quasiparticle, and should not be confused with the polaron (a fermionic quasiparticle), which is an electron plus an attached phonon cloud. Whenever the polariton picture is valid (i.e., when the weak coupling limit is an invalid approximation), the model of photons propagating freely in crystals is insufficient. A major feature of polaritons is a strong dependency of the propagation speed of light through the crystal on the frequency of the photon. For exciton-polaritons, a wealth of experimental results on various aspects have been gained in the case of copper(I) oxide.

  1. 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. Polaritons describe the crossing of the dispersion of light with any interacting resonance. Thus, a polariton is the result of the mixing of a photon with an excitation of a material. The most discussed types of polaritons are phonon-polaritons, resulting from coupling of an infrared photon with an optic phonon; exciton-polaritons, resulting from coupling of visible light with an exciton; intersubband-polaritons, resulting from coupling of an infrared or terahertz photon with an intersubband excitation; and surface plasmon-polaritons, resulting from coupling of surface plasmons with light. Recently, special kinds of polaritons, called Bragg-polaritons or Braggoritons, have been observed and studied theoretically. Whenever the polariton picture is valid, the model of photons propagating freely in crystals is insufficient. A major feature of polaritons is a strong dependency of the propagation speed of light through the crystal on the frequency. For exciton-polaritons, rich experimental results on various aspects have been gained in copper oxide.
