Extended Thermodynamics of Phonons,s, because they can exchange energy and momentum among themselves, which photons cannot do. Because of the similarity to gases it is possible to formulate a kinetic theory of the phonon gas, based on a phonon transfer equation. Peierls , was the first to do that. And that equation may ser

Kinetic Theory and Extended Thermodynamics of Metal Electrons,amics whenever the constituent particles of the body have large mean free paths, or large mean times of free flight. This situation occurs in dilute gases, and for “gases” of photons and phonons as we have seen, — but also for the electrons in a metallic conductor which carry both the electric curre
