Course description   
I will start with a short historical review of the development of the theoretical and experimental understanding of superconductivity leading up to the famous work of Bardeen-Cooper-Schrieffer (BCS). Transforming the BCS-functional into a mathematical functional of the free energy, I will first treat the translation invariant problem for general interaction potential, thereby deriving the BCS-gap equation in a general form.

This leads to the definition of the critical temperature via spectral theoretic means, and the formula for the critical temperature in the weak coupling case using a Birman-Schwinger argument. After that I will introduce external fields and present the main steps for the derivation of the Ginzburg-Landau functional (equation) close to the critical temperature.
