Rydberg Atoms and Radiation in Cavities–Quantum and Collective Effects

Rydberg atoms excited in microwave resonators are ideal systems to test quantum electrodynamics on an unusual scale.1 Owing to their very large electric dipole sizes, these atoms are indeed coupled so strongly to infrared and millimeter-wave radiation that the field of a few photons—ultimately the one of a single photon—stored in a cavity is large enough to induce important transition rates during the atomic time of flight across the cavity. As a result quantum radiative effects are observed in a range of frequencies where usual atomic systems behave as purely classical radiators. The enhancement of the spontaneous emission rate of a single atom prepared in a tuned cavity has already been observed.2 For a resonant cavity with very small losses, a point should be reached where the atom can no longer decay but instead reversibly oscillates between the two states involved in the transition resonant with the cavity mode. Experiments aimed at the observation of this new regime of quantum electrodynamics evolution are under way

Strong interaction of an atom in a high-Q cavity

G. S. Agarwal, R. Bullough, G. P. Hildred

Quantitative predictions for the quantum electrodynamics of a few atoms interacting with quantized modes of the radiation field are becoming accessible to experimental test—particularly for Rydberg atoms in microwave cavities.1 For these one needs essentially exact predictions in realistic cavities, and these show losses. At microwave frequencies1 the very few thermal photons present even at very low temperatures1 can be significant. We show in this paper that if a single two-level atom is contained in a cavity of high enough Q, interaction with a quantized cavity mode can induce new spectral features.

Free-Space Quantum Electrodynamics with a Single Rydberg Superatom

Engineering a strong interaction between a single photon and emitter could lead to novel quantum optical devices but generally requires confining the light inside a cavity. New experiments get around this requirement by coupling a few photons to a single superatom---thousands of atoms behaving as a single entity.
