Quasiparticle Many-Body Dynamics of Highly Correlated Electronic Systems
TLDR
In this article, a self-consistent theory of the correlation effects in highly correlated systems (HCS) is presented and the Irreducible Green's Functions (IGF) method is discused in detail for the Hubbard model and random Hubbard model.Citations

Electronic Dynamics of the Anderson Model. The Many-Body Approach
TL;DR: In this article, an improved interpolating solution of the Anderson model is presented, which simultaneously reproduces the weak-coupling limit up to second order in the interaction strength U and the strong coupling limit in the hybridization V (and thus also fulfils the atomic limit) can be formulated selfconsistently.

Physics of Complex Magnetic Materials: Quasiparticle Many-Body Dynamics
TL;DR: In this paper, a survey of the quantum theory of magnetism can be found, where the main emphasis is put on the dynamic behavior of two interacting subsystems, the localized spins and spin density of itinerant carriers.
