The Fluorescence Spectrum of a Single Atom on a Cavity
A single atom is an ideal laboratory in which to study the dynamical interactions of matter and radiation, and in particular the dynamical evolution of material systems in contact only with the vacuum. It is generally regarded as a fundamental tenet of atomic spectroscopy that the lower limit on fluorescence linewidths is provided by spontaneous vacuum processes. The nature of spontaneous emission in free space is well-known, but important changes can occur if the radiator is enclosed in a cavity.
