Self-consistent Greens functions in a finite model space* — •C.H. Harzer and H. Müther — Institut für Theoretische Physik, Universität Tübingen, Auf der Morgenstelle 14, D-72076 Tübingen

Single-particle and two-particle Greens functions are calculated within a self-consistent scheme for a system of Fermions within a finite model space. The results are compared to exact results, which are available for these model spaces and to the predictions of the BCS-theory. These comparisons include energies, Spectral functions and occupation probabilities for the various single-particle states.
