An Introduction to Quantum Field Theory

Publisher: University of Manchester 2008
Number of pages: 48
Presently, all observational evidence points to the fact that Quantum Field Theory (QFT) provides a good description of all known elementary particles, as well as for particle physics beyond the Standard Model for energies ranging up to the Planck scale. The scope of these lectures is to provide an introduction to the formalism of Quantum Field Theory.

Group field theories are particular quantum field theories defined on D copies of a group which reproduce spin foam amplitudes on a space-time of dimension D. In these lecture notes, we present the general construction of group field theories.

An introduction to functional integral techniques and how they can be applied in practice. Though we focus on particle physics and cosmology applications, we emphasize that these techniques can be equally applied to other nonequilibrium phenomena.

This introduction to quantum field theory will be of value not only to beginning students but also to practicing physicists interested in learning or reviewing specific topics. The material is presented in an intuitively clear and informal style.

We give a pedagogical introduction to algebraic quantum field theory (AQFT), with the aim of explaining its key structures and features. Topics covered include: algebraic formulations of quantum theory and the GNS representation theorem, etc.
