Quantum field theory - Table of contents

This is a table of contents for my notes on field theory (some classical, but mostly quantum). The posts are arranged in an order that might be found in a textbook.

These notes will be of most benefit if read in parallel with Coleman's book Quantum Field Theory: Lectures of Sidney Coleman and Lancaster & Blundell's book Quantum Field Theory for the Gifted Amateur.

Lagrangians and the action

Harmonic oscillators

First attempts at a relativistic field theory

Transformations and symmetries

Fock space and many-particle systems

Scalar quantum field

Dirac equation

From classical mechanics to quantum field theory

Quantum electrodynamics for free fields

Electron-photon interactions

Internal symmetries

Perturbation theory and the S matrix

Wick's theorem and Wick diagrams

Feynman diagrams

Crossing symmetry

Calculating scattering cross-sections
