Quantum Field Theory 1

This module is an introduction into quantum field theory, covering:

• • Action principle and Lagrangean formulation of mechanics

  • Lagrangean formulation of field theory and relativistic invariance

  • Symmetry, invariance and Noether's theorem

  • Canonical quantization of the scalar field

  • Canonical quantization of the electromagnetic field

  • Canonical quantization of the Dirac spinor field

  • Interactions, the S matrix, and perturbative expansions

  • Feynman rules and radiative corrections.
