SI2390 Relativistic Quantum Physics

SI2390 Relativistic Quantum Physics

"Relativistic Quantum Physics" is a course where important theories for elementary particle physics and symmetries are learned. During the course, it will be illustrated how relativistic symmetries and gauge symmetries can restrict "possible" theories. The course will give an introduction to perturbation theory and Feynman diagrams. The problem with divergencies will be mentioned and the concepts for regularization and renormalization will be illustrated.

Program of Lectures


Hand in assignments (INL1; 4.5 ECTS credits) and an oral exam (TEN1; 3 ECTS credits).


The examination of the course will be a combination of homework problems (INL1) and an oral examination (TEN1).
INL1. There will be three sets of homework problems, which each consists of two parts, during the course. These will be distributed and should be handed in according to the following scheme:

TEN1. The oral examinations will take place after the last lecture of the course. Each examination will take approximately 15 minutes. The time for the examination will be agreed upon between the student and the examiner.


The different grades are: A, B, C, D, E, Fx, and F. The grades will be awarded according to the following scheme:
GradeHomework Problems (INL1)Oral Examination (TEN1)
F< 50% of all problems correctFailed
Fx< 50% of all problems correctPassed
Fx≥ 50% of all problems correctFailed
E≥ 50% of all problems correctPassed
D≥ 60% of all problems correctPassed
C≥ 70% of all problems correctPassed
B≥ 80% of all problems correctPassed
A≥ 90% of all problems correctPassed
In addition, you need to obtain at least 50 % on each homework problem set in order to obtain a passing grade (E or higher). If you obtain a total result of more than 50 %, but do not fulfill this criterion, you will be given the grade Fx and a chance to make a completing task for the grade E. For PhD students, the different grades are: F (fail) and P (pass).
