A phonon is a quantum of energy of the independent oscillators in the ensemble. ... All Answers (12) phonons are a way to describe the vibrational degrees of freedom in periodic structures (lattices): the vibrational motions can be modelled as harmonic oscillators, so they can be quantized nearly in the same way.
A phonon is a quantum unit of sound. It is the lowest energy, quantized state of a vibration within a lattice structure, such as those created by the atoms of matter. The name phonon comes from the behavior of long-wavelength phonons, which give rise to sound at higher energy levels. In quantum physics, the principle of wave particle duality indicates that behavior which is normally treated as a wave (such as sound) can also be treated as a quantized particle: the phonon.
