The atom-field interaction is formulated within the fully quantized-field theory, starting from a detailed analysis of the transformation from the fundamental minimal coupling interaction Hamiltonian to the electric dipole Hamiltonian used extensively in quantum optics. Spontaneous emission, radiative level shifts, and the natural radiative lineshape are treated in both the Schrodinger and Heisenberg pictures, with emphasis on the roles of vacuum field fluctuations, radiation reaction, and the fluctuation-dissipation relation between them. The shortcomings of semiclassical radiation theories are discussed.
期刊介绍：
Nonlinear Optics and Quantum Optics publishes primary papers reporting original research, review articles and rapid communications. The journal is divided into four main sections: 1. Principles: covering studies into the fundamental theoretical understanding of the origins and mechanisms of nonlinear optical processes; theoretical studies of application of controlled optical field to quantum information processing including quantum communication and computation and fundamental problems of quantum mechanics related to quantum information processing.
