Quantum Field Theory

Quantum Field Theory (University of Cambridge). This is a collection of lecture videos on quantum field theory given by Professor David Tong, a theoretical physicist at the University of Cambridge. The videos were recorded from the lectures given at the Perimeter Institute PSI programme in 2009. They are accompanied by lecture notes, covering the canonical quantization of scalar fields, Dirac fields and QED. These lecture notes are based on an introductory course on quantum field theory, aimed at Part III (i.e. masters level) students. The full set of lecture notes can be downloaded here.
