Due to the COVID pandemic, please register via the KSL if you are planning to take this course (or contact me in case this is not possible)!

Course description

First (of two) semester of a basic course on quantum field theory. The course subjects include:

  • path integral quantization of the free scalar field
  • continuous spacetime symmetries in classical field theories
  • Feynman diagrams 
  • canonical quantization of the scalar field
  • continuous symmetries in QFT
  • internal symmetries (continuous and discrete)
  • spontaneous symmetry breaking
  • the fermion field

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 "Exercices in Theoretical Physics" and before "Quantum Field Theory II" (Spring semester).
