Abstract:The von Neumann-Landau equation describes the change in the density matrix with time. Interestingly, this equation was recently regarded as a wave equation for wave functions but not a equation for density functions. This setting leads to an extended form of the Schrödinger wave equation governing the motion of a quantum particle. In this paper we obtain integrability of wave propagator arising from the von Neumann-Landau equation in this setting.
