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.

Prerequisites

The following courses are mandatory: The following course is recommended:

Program

Requirements

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

Examination

The examination of the course will be a combination of homework problems and an oral examination. There will be three sets of homework problems during the course. These will be distributed and should be handed in according to the following scheme:
Homework problemsOutIn
Set #1Lecture 5 (January 24, 2017)February 7, 2017
Set #2Lecture 11 (February 7, 2017)February 22, 2017
Set #3Lecture 17 (February 27, 2017)March 13, 2017
The oral examinations will take place after the last lecture of the course. Each examination will take approximately half an hour. The time for the examination will be agreed upon between the student and the examiner, but the student is obliged to take contact with the examiner.

Grading

The different grades are: A, B, C, D, E, Fx, and F. The grades will be awarded according to the following scheme:
GradeHomework problemsOral examination
F< 40% of all problems correctFailed
Fx< 40% of all problems correctPassed
Fx≥ 40% of all problems correctFailed
E≥ 40% 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
For PhD students, the different grades are: U (fail) and G (pass).
