Abstract

The rigorous formulation of quantum optics often starts with the nonrelativistic minimal interaction Hamilton for the atoms and field, and a set of temporal equations of motion for the annihilation operators are then derived. In many experiments, however, it is necessary to describe the spatial propagation of the electromagnetic field. Usually this is done by heuristically replacing the time variable by a space variable. Because of this ad hoc way of obtaining spatial propagation, it is not possible to compare the results of traveling-wave quantum optic experiments with the fundamental quantum electrodynamic theory. The authors provide the missing link between the theory and experiments by rigorously treating spatial propagation in an atomic medium within the framework of quantum electrodynamics. They find important differences between their approach and the conventional approaches, even for the simple case of a lossless refractive medium.
