The course is meant to give an overview of renormalisation group (RG) methods in various areas of condensed matter physics. It is expected that students have a general knowledge of statistical mechanics and know something about field-theoretic methods. The course should make them able to apply RG methods to problems in their own research.
Texts:
For the most part, the course will follow the book “Scaling and renormalisation in statistical physics” by John Cardy (Cambridge U Press). The plan is to provisionally base the material on fermion systems on the article “Renormalisation-group approach to interacting fermions” by R Shankar (Rev Mod Phys 66, 129-192 (1994). Recent papers on topics of current interest will also be used.
