SI2410 Quantum Field Theory 7.5 credits
"Quantum Field Theory" is a course in which one should learn functional integral formalisms for quantum field theories. In addition, important examples of quantum field theoretical models in particle physics and condensed matter physics will be discussed. The concepts of renormalization and regularization in quantum field theory will be described and the idea of effective models will be mentioned.

Examination and completion
If the course is discontinued, students may request to be examined during the following two academic years.
Grading scale
A, B, C, D, E, FX, F
Examination
- INL1 - Assignments, 4.5 credits, grading scale: A, B, C, D, E, FX, F
- TEN1 - Examination, 3.0 credits, grading scale: A, B, C, D, E, FX, F
Based on recommendation from KTH’s coordinator for disabilities, the examiner will decide how to adapt an examination for students with documented disability.
The examiner may apply another examination format when re-examining individual students.
Other requirements for final grade
Hand in assignments (INL1; 4.5 hp) and an oral exam (TEN1; 3 hp).
Opportunity to complete the requirements via supplementary examination

Ethical approach
- All members of a group are responsible for the group's work.
- In any assessment, every student shall honestly disclose any help received and sources used.
- In an oral assessment, every student shall be able to present and answer questions about the entire assignment and solution.
