Content: Fock space - Second Quantization. Many-particle Green's functions - Matsubara formalism. Linear Response Theories. Dielectric formulation in long-range interaction (Coulomb) systems and self-consistent theories of Screening. Phase diagram of Interacting Electrons (including the Wigner Crystal Phase). Functional Integrals and Hubbard-Stratonovich transformation: application to Plasmons and Cooper Pairing (Nambu-Gorkov fοrmalism) for Superconductivity, but also for electron-hole pairing in the Excitonic Insulator Phase.
