# QFT: Quantum Field Theory

Posted September 26th, 2016 by mpags

Lecture 2: Preliminaries (Quantum) - Canonical Quantization, Schrödinger, Heisenberg & Interaction Pictures, Harmonic Oscillator

Lectures 3-4: Free Fields - Canonical Quantization, Vacuum State, Particle States, Causality, Feynman Propagator

Lectures 5-6: Interacting Fields - S-Matrix, Wick’s Theorem, Feynman Diagrams, examples

Lecture 7: Spinors - Lorentz Group, Spinor representation

Lecture 8: Dirac Equation

Lectures 9-10: Quantization of Dirac Equation - Fermions, Feynman Rules, examples

## Module title: Quantum Field Theory (QFT)

### Module convenor: Dr Tasos Avgoustidis (Nottingham)

### Module Aims:

This module will provide an introduction to Quantum Field Theory, designed to follow-on from PP2: Relativistic Quantum Mechanics. We will construct Feynman rules from first principles and use them to study elementary processes involving scalars and fermions. Our approach will be through canonical quantisation. This is an introductory course, which will not cover renormalisation. For QED and non-abelian gauge theories, see module PP3.### Syllabus
