Lecture: Quantum Optics (WS13/14)
Lecturer: Norbert Schuch
Overview
Quantum Optics deals with the quantum mechanical description of light and its interaction with matter. This lecture will provide an introduction to the field of quantum optics, covering the basics of the field as well as recent developments such as the controlled manipulation of individual photons and atoms using e.g. cavities or ion traps.
Planned topics include:
- Quantization of the light field
- States of the light field: Coherent states, squeezed states, Fock states
- Non-classical statistics of qu antum mechanical light
- Interaction of light with matter: The Jaynes-Cummings model
- Noise in quantum optics, spontaneous emission and absorption
- Collective effects, superradiance, lasers
- Manipulation of atoms and light in cavities and ion traps
- Light forces on atoms, laser cooling, optical lattices
Prerequisites
Quantum mechanics ( ideally including basics of second quantization and mixed states), and basics of electrodynamics.
