Program

In the course I shall present some practical applications of the Feynman diagram technique discussed in the preceding course. In particular, I will cover the following topics:

  • Hamiltonian of matter coupled to a quantised electromagnetic field. Meaning and consequences of gauge invariance. Optical response of a metal.
  • Landau-Fermi liquid theory.
  • Conserving Hartree-Fock approximation applied to model band insulators, and the emergence of excitons.
  • Disordered metals.
