Handbook of Atomic, Molecular, and Optical Physics

Atomic, molecular and optical physics (AMO Physics) is the study of the interaction between light and matter. These interactions are investigated on various scales (from the atomic to molecular level) with the purpose to find answers to important scientific questions. All that is the driving reason to extent the research opportunities in atomic, molecular and optical physics to a broad range of topics. The first part of the book presents the leading investigations in the theoretical and experimental study of the atomic systems. The Hartree-Fock and multiconfiguration Hartree-Fock methods are discussed on the example of neutral oxygen. The Greens function technique is used for the calculation of self-interaction part of the GW self-energy on atomic hydrogen. A relativistic model for valuating of radiation transition parameters in spectra of multicharged ions is described. The experimental aspect of the atomic physics by describing in details the flame atomic absorption spectrometry for determining of trace amount of metals is also included in the book. The second part starts with a discussion of molecular structures from computational and theoretical perspective. A larger space is given to the application of the DFT methods to systems at different levels of complexity and nature. A theoretical study of topological indices of a molecular structure, which can provide us a basis for the manufacturing of drugs and chemical materials without using of experiments, is also discussed. The last articles of this book section look at the experimental aspects of the molecular physics involving various types of spectroscopy. A brief description of the basic ideas behind these techniques is given, with emphasis on the Raman, Electronic, Infrared, NMR, X-Ray and Mass spectroscopy. The last part of the book presents a collection of articles whose main topic is the optical physics, which studies the dynamical interactions of atoms and molecules with electromagnetic fields. Michelson-Morley Interferometer (MMI) is an example of an optical device where one, in terms of intensity measurements, can exhibit the difference between classical and quantum-mechanical light. Other optical devices that have wide applications are the lasers. Moreover, nonlinear phenomena have many attractive features for modifications of optical properties, but its potential has not been yet fully explored. Here are discussed examples of nonlinear pulse shaping in fibres both for pulse generation and for nonlinear light emission of single gold optical antennas.
