A Comparison between Approaches for Deriving Kinetic Equations for a Dilute Inhomogeneous Quantum Gas
Michel De Haan
Abstract
The kinetic equation proposed by Nacher, Tastevin and Laloë is placed in the general framework for deriving kinetic equations by a systematic analysis of the hierarchy of equations for the time evolution of the Wigner distribution functions (Wdf). We prove that the stationary solution of their equation can be identified with the equilibrium one-particle distribution function in the grand canonical ensemble.
