Introduction to modern atomic physics. The fundamental concepts and modern experimental techniques will be introduced. Topics will include: Two-state systems, magnetic resonance, interaction of radiation with atoms, transition probabilities, spontaneous and stimulated emission, dressed atoms, trapping, laser cooling. Structure of simple atoms, coupling to fields, light scattering. Fundamental symmetries and introduction to molecules and artificial atoms. Selected experiments. The first of a two-term subject sequence that provides the foundations for contemporary research.
