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
