Course Description
This course constitutes the first part of a two-semester introduction to Quantum Field Theory. The topics covered or briefly addressed include:
- Canonical quantization of scalar fields (classical field theory in Lagrange and Hamilton formalisms; canonical quantization; differently time-ordered propagators; interactions; S-matrix; Green's functions; LSZ-reduction; perturbation theory)
- Path integral quantization of scalar fields (path integral in quantum mechanics and field theory; Wick's theorem; Schwinger-Dyson equations and generating functionals)
- Renormalization (power counting; regularization; bare and renormalized Green's functions; renormalization group)
