Abstract
The quantum Fokker-Planck equation for the irreversible evolution of a bath of interacting oscillators is derived with sufficient generality that both the action and angle dependence of the distribution functio n are maintained in the classical limit. This approach unifies Landau- Rumer processes, spontaneous phonon decay, quantum renormalization of the speed of sound, and quantum wave turbulence.
