PY4T02: Electron & Photon Physics Part 1

Quantum Theory of Light

Paul Eastham


Indicative Syllabus

  1. Introduction
  2. Planck radiation law
  3. Photon shot noise
  4. More intensity fluctuations: single-mode thermal field, classical chaotic light
  5. Hamiltonian for the electromagnetic field
  6. Classical and non-classical state of light -- coherent states, number states. Visualising field distributions.
  7. Light-matter interactions -- Jaynes-Cummings model and Rabi oscillations. Generation of coherent states with classical dipoles.
