Overview of modern experiments in atomic optics: atomic clocks, masers, cooling of atoms, optical and magnetic traps, Bose - Einstein condensation, optical lattices, atom interferometry, magnetometry, quantum science with individual atoms and atom files. Interaction of atoms and optical radiation, description of the interaction using basic types of Hamiltonians: dipole approximation, the rotating wave approximation. Quantization of the electromagnetic field in free space. A two-level atom in a single-mode field, dressed states, Bloch equations, Rabbi oscillations, resonance fluorescence, Mollow splitting. Applications for the maser and atomic clocks. A two-level atom interacting with a multi-mode field; Wigner-Weisskopf theory of spontaneous emission. Homogeneous and inhomogeneous spectral line width. Optical field with modified spectra, photonic crystals, whispering gallery mode resonators, Zeno and anti-Zeno effect. Mikromasers, evidence of quantization of electromagnetic fields in resonators. Atom trapped in a field of a single photon. Multi-atomic systems interacting with a single-mode optical field. Dicke states, superradiance and superfluorescence. Self-induced transparency, optical solitons in resonant environments. Model of a multi-state atom, fine and hyperfine structure. Clebsch-Gordan coefficients, Stark shift, Raman scattering and STIRAP, electromagnetically induced transparency. Application for magnetometry and quantum information processing.
