Phase Space Description,on is the one that resembles more closely the classical probability. On the other hand, the .-distribution originates from representing the density operator as an ensemble of coherent states and the .-representation is a description of the density matrix via its diagonal elements, again, in a coherent state basis.

,Einstein’s Theory of Atom-Radiation Interaction,sults paved the way for an understanding, in a qualitative way, of the basic ingredients of the atom-radiation interaction, and could be useful for describing the processes of absorption, light scattering by atoms, stimulated emission in a variety of laser and maser systems, etc. This happened after

Phase Space Description,e field can be described by complex functions of .. These methods are of considerable practical interest, since one is dealing with functions rather than operators. The most common representations in phase space are the Glauber distribution, and the . and Wignerrepresentations. The Wigner distributi

,System—Reservoir Interactions,vant system (the atom) interacting with a large reservoir consisting of an infinite number of harmonic oscillators or electromagnetic modes. It appears quite surprising that starting from time-reversible dynamics, one ends up in an irreversible situation, such as the natural decay of an excited atom
