Abstract
The atom-field interaction is treated in semiclassical radiation theory, starting from the transformation from the minimal coupling Hamiltonian to the electric dipole form used extensively in quantum optics. The Heisenberg and density matrix approaches are developed and applied to two-state atoms, Bloch equations, Rabi oscillations, Maxwell-Bloch equations, and transition rates for absorption and emission. Einstein’s theory of blackbody radiation based on momentum fluctuations and dissipation is reviewed. The Einstein fluctuation formula is derived and used to introduce wave-particle duality, Hanbury Brown-Twiss correlations, and photon bunching.
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.
