IRREVERSIBILITY IN A GENERALIZED WIND TREE MODEL,
Abstract
The irreversible behavior of a particle under the influence of fixed scattering centers is investigated in the weak coupling limit. An ensemble is introduced which statistically describes the scattering centers as well as the particle. This allows the treatment of correlations between the particle and the scattering centers. A new diagrammatic method is used to investigate high order terms in the perturbation theory. This method yields quite explicit information about the way that the influence of initial correlations will disappear. In particular it is quite clear that as one goes to higher order in the perturbation theory one must wait longer times for the influence of initial correlations to disappear. For completeness the Boltzmann equation is derived and solved to lowest order in the interaction strength. (Author)
