Conformal symmetry is a powerful tool for studying critical behaviour, particularly as applied to two-dimensional classical systems, and to quantum systems in one dimension. The mathematical tools of conformal field theory are also important in string theory, as well as for their own interest.
This advanced graduate course will attempt to present the basic physical ideas and relate them to the mathematics in the simplest possible way. The emphasis will be on applications to two-dimensional critical behaviour. A knowledge of the basics of quantum field theory and its application to critical behaviour, as given in the Michaelmas 2009 QFT course (complete lecture notes here) will be assumed, although a brief review will be given at the beginning of the course. A familiarity with the role of the stress-energy tensor in field theory would also be useful, as well as the basics of complex analysis.
The lectures will be based on my 2008 les Houches lectures, and, depending on time, cover the following topics:
Lectures will be on Mondays and Wednesdays at 10 am in the Fisher Room, except for the following dates:
