Inhalt In this lecture concepts of modern many-particle theory will be introduced. The lecture mainly deals with the calculation of equilibrium Green functions, which build the basic quantity of the theory.

After an introduction of how and to what extent physical quantities are connected to Green functions, some basic formal properties of the latter are introduced. The concepts of Feynman diagrammatic perturbation theory are developed next and then applied to some problems:

  1. Dynamical susceptibility of the interacting electron gas,
Lindhard screening
  1. Nambu-Gorkov formulation of the BCS theory
  2. Phonons
Vorkenntnisse Quantum mechanics and statistical physics
