SUMMARY:Wigner distribution functions for complex dynamical systems 
DESCRIPTION:Featuring Dries Sels\, Universiteit Antwerpen\nHosted by: Luca 
	D'Alessio\n\nPart of the Condensed Matter Theory Seminar Series.\n\nAbstrac
	t:\n\nThe equation of motion for the reduced Wigner function of a system co
	upled\nto an external quantum system is presented for the specific case whe
	n the\nexternal quantum system can be modeled as a set of harmonic oscillat
	ors.\nThe result is derived from the Wigner-Weyl formulation of the\nFeynma
	n-Vernon influence functional theory for the reduced propagator.  It\nis sh
	own how the true self-energy for the equation of motion is connected\nwith 
	the influence functional for the path integral. Explicit expressions\nare d
	erived in terms of the bare propagator. It will be shown under\nwhich appro
	ximations the resulting equation of motion reduces to the \nBoltzmann equat
	ion.
