Quantum statistical approach to extended mean-field theory

III. Collisions Terms
Part of the Lecture Notes in Physics book series (LNP, volume 171)


The time-dependent Hartree-Fock theory is generalized in order to include two-body collisions. Using the projection operator techniques of statistical mechanics a transport equation is derived for the uncorrelated part of the full A-particle density matrix. This leads to an equation of motion for the one-particle density matrix which includes a collision term. The collision term is considered in the weak-coupling limit and a master equation is obtained for the occupation probabilities of the single-particle levels.
