Title Quantum Field Theory I
Description First semester of a 2-semester basic course on quantum field theory. The course subjects include:

Part I: QFT of the scalar field
- canonical quantization of the free scalar field
- Wick's theorem and the scattering amplitude
- Feynman diagrams and Feynman rules for phi4 theory
- example calculations of various scattering amplitudes
- continuous symmetries in QFT
- internal symmetries (continuous and discrete)

Part II: QFT of the fermion field
- representations of the Lorentz group
- the Dirac Lagrangian and equation
- Clifford algebra and gamma matrices
- canonical quantization for spinors
- Feynman rules

Part III: QFT of the photon field and QED
- canonical quantization of the electromagnetic field
- coupling to fermions -> QED and its Feynman rulees
- coupling to scalars -> sQED and its Feynman rules
- calculation of simple processes in (s)QED
- introduction to loop corrections and renormalization

The exercise sessions and exercise sheets are integral part of the course, as some essential concepts are developed there!

This course should be attended in parallel with "Exercises in Theoretical Physics" and before "Quantum Field Theory II" (Spring semester).

Please register for the course in advance via the KSL.
