Quantum Field Theory
Quantum Field Theory, 6hp, September-December 2013
Responsible: Magnus Johansson, E-mail majoh@ifm.liu.se
Short course content:
The aim is that the students should get introduced to some basic concepts and methods from
Quantum Field Theory. The course will be organized as a Study Group, with roughly one meeting per
week during the autumn. Active students are expected to present various parts of the topic
themselves at the meetings, as well as to solve homework problems. Important concepts that will be
treated are the use of Feynman diagrams, propagators and Feynman rules to describe interacting
fields and elementary processes in Quantum Electrodynamics, as well as an introduction to path
integrals, functional quantization and renormalization. A more detailed choice of topics will be
decided together with the participants at course start. Course literature will be decided in August.
The course will be aimed both at PhD-students and advanced undergraduate students. Necessary
prerequisites:
(i) Knowledge of Quantum Mechanics at the level of either the undergraduate course TFYA28
Quantum Dynamics, or the PhD-courses Quantum Mechanics I and II. In particular, students will be
assumed to have seen the Dirac equation before.
(ii) Knowledge of Electrodynamics at the level of either the undergraduate course TFYY67 Classical
Electrodynamics, or the PhD-course Electrodynamics (7.5hp).
(iii) Knowledge of Classical Mechanics at the level of the undergraduate course TFYA40 Analytical
Mechanics.
(iv) Basic concepts in special relativity such as Lorentz-transformations and four-vectors (should be
contained in (i)-(iii)).
