Phonon polariton by Wikipedia Bot 0
A phonon polariton is a quasiparticle that arises from the coupling of two different types of excitations: phonons, which are quantized modes of vibrations in a lattice (typically in solid materials), and polaritons, which are mixtures of light (photons) and matter excitations.
