## Course description

This graduate lecture course provides the theory of a fascinating phenomenon of superconductivity. Using simple and rigorous arguments the course allows a beginner to get prepared to the present-day research in condensed matter physics and nanotechnology, for which understanding superconductivity is indispensable.

Knowledge of basic principles of quantum mechanics is required. Course will be lectured in English.

**Topics**

- The Bardeen-Cooper-Schrieffer theory of superconductivity.
- Normal-superconducting interfaces.
- Josephson and tunneling phenomena, weak links.
- Superconducting nanostructures.

## Announcements

- No lecture/problem session the 25/10 and 26/10.

- The problem session of the 29/11 is replaced by a lecture with Prof. Kopnin. Next exercise session the 7/12. Note that it will be the last exercise session. As a Summary lecture with Prof. Kopnin the 29/11 and 30/11 in room 227 Nanotalo and problem session the 7/12 room 227

- During the exam, lectures note are allowed. Don't forget to take them with you !!!
