Lecture of Interest -Cooperative Spontaneous Emission and Scattering of Light:A Theory of Coherent Radiation Damping

A quantum radiated by any one of a collection of identical atoms may be absorbed by others and re-emitted many times before it emerges. The radiation is thus best described as a collective process. It takes place only in certain favored modes that have a particular range of decay lifetimes and corresponding ranges of spectral level shifts and linewidths. The light that these atoms scatter resonantly also reflects this complex spectral structure.
