Lecture course "Quantum Field Theory II", WS 2013/14

Quantum field theory is a universal tool which has applications ranging from condensed matter physics to elementary particle physics. A crucial role is played by symmetries which are at the heart of the universality shown by many physical systems. In this lecture the focus will be on aspects of symmetry breaking and collective phenomena. We will also expand on the ideas of renormalization, gauge theories and topological phases of matter.

Outline of topics:

Prerequisites: Quantum Field Theory I.

Time and location: Wed 8-10h (Lecture Hall II) and Fri 14-16h (Seminar Room PH I). Exercises: Thu 10-12h (Seminar Room PH II).
Lecturer: PD Dr. Thomas Quella
Exercises: Dr. Dmitry Bagrets and Dr. Vladimir Osipov

Note: Hand-written lecture notes are available on request. The lecture is following the book "Condensed Matter Field Theory" (2nd edition) by Altland and Simons. The books "Field Theories of Condensed Matter Physics" by Fradkin and "The Quantum Theory of Fields I & II" by Weinberg are suggested as an additional reference for advanced readers who wish to broaden their perspective.
