This course provides you with a basic understanding of quantum field theory, based on quantum mechanics and special relativity. You will learn about the Klein-Gordon and Dirac equations, which describe free scalar particles and fermions, as well as their quantization. The course shows how interactions can be included using perturbation theory and Feynman diagrams, which will help you calculate various processes in quantum electrodynamics.

The course concludes with an introduction to higher-order processes and radiation corrections.

This course can be part of a program in physics or astrophysics, or taken as a free-standing course.

The course focuses on providing you with practical skills in using quantum field theory to solve physical problems.

The course consists of lectures and calculation exercises. You will work on written assignments during the course and conclude with an oral theory exam. To participate in the oral exam, you must have passed all assignments. 

Applications for this course are currently closed.

You can find information about future application opportunities here.
