SUMMARY
A polariton is a quasi-particle that arises from the coupling of an electronic dipole transition in a material with an applied electromagnetic field, specifically a photon. This concept is crucial for understanding the localized response of materials when interacting with light. Notable examples of polaritons include optical phonons and surface plasmons, which illustrate the diverse applications of this phenomenon in material science and photonics.
