The course can be seen as a continuation of solid state theory I, where now the emphasis is put on a more in-depth look at typical solid state phenomena and the methods for their description.
The course will start with an introduction to modern techniques for treating interacting quantum many-body systems. These methods will then be applied to several problems of condensed matter physics, such as magnetic impurities in a metal (Kondo effect), electron motion in a random potential, and superconductivity.
These physical problems will also serve as examples where more advanced methods and notions, like renormalization group or critical behavior at phase transitions, will be discussed.
