Quantum Field Theory


Admission Requirements

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.

Course Objectives

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
