Photon wave packet dynamics and resonant atom-photon interaction inside a parabolic cavity — •Johan David Eggers, József Zsolt Bernád, and Gernot Alber — Institut für Angewandte Physik, Technische Universität Darmstadt, D-64289 Darmstadt

The evolution of a single-photon electromagnetic wave packet is investigated, which is generated by a spontaneously decaying two-level system located at the focus of a parabolic half-open cavity with ideally conducting walls. In the rotating wave and dipole approximation a multiple scattering formalism is developed which represents relevant quantum mechanical probability amplitudes as sums of contributions of photonic paths in the cavity which have been scattered by the two-level system repeatedly. This photon-path representation is particularly well suited for describing the photonic wave packet dynamics in the semiclassical limit of small photonic wave lengths. Furthermore, it gives physical insight into the nature of the quantum electrodynamical light-matter interaction and its modification by boundary conditions.
