Prerequisites: Effective Field Theory, Quantum Theory.
Building on the courses Effective Field Theory and Quantum Theory, this is a first course in the Quantum Theory of Fields, which consistently unifies special relativity with quantum mechanics, and allows the description of many simultaneously quantized excitations.
A basic understanding of the topics listed below, including the ability to do computations of the most important effects.
• Quantum Mechanics from a Lagrangian perspective
• The path integral
• Spin and the Lorentz Group
• The Dirac Equation
• The theory of Quantum-ElectroDynamics
• Perturbation theory and elementary scattering processes
• Introduction to Renormalization, the renormallization group and the connection with critical phenomena
