Synopsis:

The lecture covers basic and advanced topics of quantum theory of interaction and coherence. The attention is given to time dynamics of quantum systemsand, based on nonstationary perturbation theory, both semiclassical and fully quantum theory of interactionof quantum systems with electromagnetic field, together with the quantum theory of optical scattering. It is further devoted tostatistical properties of radiation, coherent states of quantized electromagnetic field, quantum optical radiationdescription, and specific states of the field. It also introduces quasiprobability densities and quantum characteristic functions, in relation to classical ones. Finally, theattention is given toquantum theory of damping, nonclassical measurement techniques, and selected topics of modern quantum optics.
