Faglig innhold

Lorentz invariance and second quantization, classical field theory and classical symmetries, perturbation theory, S-matrix and LSZ, Feynman rules, quantum electrodynamics (QED), spin-1 and gauge invariance, spinors, spinor solutions and CPT, spin and statistics, path integrals, Casimir effect, renormalized perturbation theory, infrared divergence, renormalizability, and non-renormalizable theories.

Læringsutbytte

By the end of the course, students will understand the theoretical foundations of relativistic quantum field theory and be able to construct and quantize Lorentz-invariant field models, analyze their symmetries, and compute scattering amplitudes using perturbative methods. They will acquire practical skills in applying path-integral and canonical formalisms, gauge invariance, and renormalization techniques, and be able to interpret key physical phenomena such as the Casimir effect and quantum vacuum fluctuations.
