Quantum Theory of Condensed Matter II
Lecture details
The summer semester is held as a digital semester. In principle, as agreed by the universities in North Rhine-Westphalia, all courses that can be offered remotely will take place online for the entire summer semester.
The lecture will be given by Prof. 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
- Collective 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
Prerequisites:
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
