# Quantum Theory of Condensed Matter II

## Lecture details

The lecture will be given by Professor Schoeller.

**Description:**

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
- Topology in condensed matter systems: Majorana fermions, anti-unitary and chiral symmetries, classification of topology, topological invariants, SSH model, Kitaev chain, quantum Hall effect, Floquet theory and Floquet topological insulators
