Synopsis:

The lecture provides an introduction into quantum field theory. The actual treatment is provided by means of functional integrals. Central part of the lecture revolves around particle physics. In this connection, the quantization of simple systems (scalar fields, fermionic fields and gauge fields) is outlined and the corresponding perturbation treatment of Green's function is discussed via Feynman integrals. We further cover topics such as quantum field theory at finite temperature, renormalization group methods and spontaneous breakdown of symmetry. Essential part of the lecture consists of the problem solving. Handouts are provided.
