Course Description

This is the first of a two-semester subject sequence that provides the foundations for contemporary research in selected areas of atomic and optical physics. Topics covered include the interaction of radiation with atoms: resonance; absorption, stimulated and spontaneous emission; methods of resonance, dressed atom formalism, masers and lasers, cavity quantum electrodynamics; structure of simple atoms, behavior in very strong fields; fundamental tests: time reversal, parity violations, Bell's inequalities; and experimental methods.

MAIN TOPICS:
- The two-state systems: Resonance
- Atoms—electronic structure
- Helium atom
- Fine structure and Lamb shift
- Hyperfine structure; Magnetic fields
- Atoms in electric fields
- Interaction of an Atom with an Electro-Magnetic Field
- Einstein's A and B coefficient
- Saturation of transitions
- Line shapes
- Two-photon transitions
- Coherence
- Dicke superradiance
