Advanced Quantum Field Theory (882F3)

15 credits, Level 7 (Masters)

Spring teaching

In this module, you will learn an advanced formulation of Quantum Mechanics and Quantum Field Theory (QTF) in terms of the path integral formalism and of generating functionals for Green's functions. This formulation will allow you to discuss an elegant quantisation of Abelian and non-Abelian gauge field theories.

You will study QFTs at one-loop in perturbation theory, which requires the computation of divergent loop diagrams. This observation will lead you to a discussion of renormalisation and of renormalisation group equations. The concept of asymptotic freedom will be introduced. A short introduction to QFT methods in quantum gravity will be provided.
