Quantum Theory of Condensed Matter II


Lecture details

This lecture will be given by Professor Schoeller.


This course is a continuation of the course on "Quantum Theory of Condensed Matter I". It contains the following subjects:

  • electrons and phonons: screening properties, effective phonon propagators and quasiparticle life-time
  • BCS-superconductivity: BCS model, BCS theory, mean-field theory, transverse electromagnetic fields
  • Collective magnetism of insulators: Heisenberg model, mean-field theory, spin wave theory
  • Collectivce magnetism of metals: spin density waves, Ferromagnetism, Antiferromagnetism
  • Superfluidity: Bose-Einstein condensation, mean-field theory
  • Disorder: metals and superconductors,
  • Linear transport theory: Kubo formula, disorder, conductivity, linear Boltzmann equations, weak localization
  • Introduction to path integral methods


Quantum Theory of Condensed Matter I:
second quantization, quantum decay theory, basic knowledge about electrons and phonons, Jellium model, longitudinal acoustic phonons in continuum theory, Green's functions and correlation functions, Kubo formalism, Matsubara Green's functions, self-energy, Wick's theorem and Feynman diagrams, dielectric function and screening theory, Fermi liquid theory
