On Quantum Beat Phenomena and the Internal Consistency of Semiclassical Radiation Theories
The past decade has seen many successful applications of semiclassical radiation theory. In these calculations matter is treated quantum mechanically while radiation is described according to Maxwell’s equations. In fact, if one adds “vacuum fluctuations” to this semiclassical picture, it would seem that we have all that we need to understand everything from spontaneous emission and the Lamb shift to superfluorescence and the laser linewidth in a semiquantitative fashion.
