Office hours: Wed, 15:00-16:00

This course provides an introduction to the basic concepts of the Renormalization Group and application to different fields in physics. A special focus is put on the theoretical description of phase transitions and critical phenomena. The lecture will be held in English, but questions and discussions in German are of course welcome.
