摘要
A self-similar description of electron and phonon kinetics in metals with a sharp gradient of the electron temperature is developed. A nonequilibrium distribution of the phonon number density is derived, which is peaked near the ion plasma frequency and is extended along the heat-flow axis. It is shown that the Cherenkov generation of nonequilibrium phonons results in suppression of the electron heat flux and rapid disintegration of the metal lattice.
