Course Content

The combination of quantum mechanics with the laws of special relativity requires the introduction of a new framework: relativistic quantum field theory. This course introduces the concepts and techniques of quantum field theory using a realistic theory: quantum electrodynamics (QED). This is the theory which provides a microscopic description of electrically charged particles interacting through the electro-magnetic force.

After introducing the free Maxwell and Dirac fields, interactions are introduced in a systematic way. The full theory is then treated using time dependent perturbation theory - translated in the form of Feynman diagrams and rules.

Subsequently we use this to analyze several standard processes in QED: pair production, scattering in an external field, Compton scattering, ...

Next radiative corrections are studied thereby introducing the concepts of regularization and renormalization. The course ends with a brief introduction to the generalization of QED to the other fundamental interactions.

Additional info

The full course is taught by A. Sevrin. This course can be chosen by the first master year of physics students of the KU Leuven as well. In principle the course is taught in Brussels.

There are 5 teaching days - spread over the semester - each of which starting at 9 am and ending at 3 pm. Some days will be in person teaching on the VUB campus, some days will be taught remotely.

The exercises are given in the form of homework. The homework will be corrected and particular problems will be discussed in class.

Learning Outcomes

General Competencies

Relativistic quantum fiel theory is a new conceptual layer in physics relevant when studying natural phenomena at small scales where the laws of quantum mechanics and special relativity apply simultaneously.

The course aims at a good understanding of the foundational principles of quantum field theory while simultaneously the student will enlarge his technical and analytical skills such as to be able to analyze complex realistic problems.

As quantum field theory is one of the basic topics in theoretical physics, the course provides the foundation for numerous other courses.

 

Grading

The final grade is composed based on the following categories:
Oral Exam determines 33% of the final mark.
PRAC Paper determines 33% of the final mark.
SELF Practical Assignment determines 34% of the final mark.

Within the Oral Exam category, the following assignments need to be completed:

  • Oral exam with a relative weight of 33 which comprises 33% of the final mark.

    Note: The exam will be online and individually.

Within the PRAC Paper category, the following assignments need to be completed:

  • Final paper with a relative weight of 33 which comprises 33% of the final mark.

    Note: At the end of the course you write a short paper on a topic related to the course.

Within the SELF Practical Assignment category, the following assignments need to be completed:

  • Homeworks with a relative weight of 34 which comprises 34% of the final mark.

    Note: After every lecture you will receive a homework assignment which will be corrected and graded.

Additional info regarding evaluation

The homework assignments count for 1/3 of the final score. The final paper together with its presentation is another 1/3 of the final score. An oral discussion on the most important concepts addressed in the course provides the final 1/3 of the points.

Allowed unsatisfactory mark
The supplementary Teaching and Examination Regulations of your faculty stipulate whether an allowed unsatisfactory mark for this programme unit is permitted.
