Lecture course "Quantum Field Theory I", SS 2011

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 foundational aspects of quantum field theory, with emphasis on condensed matter applications. Someone who is interested in going into high energy physics is recommended to attend a different lecture with focus on relativistic quantum field theory and quantum electrodynamics such as it is currently offered by Prof. A. Klemm in Bonn.

Outline of topics:

Prerequisites: Solid knowledge in quantum mechanics.

Note: Hand-written lecture notes are available here.
