Rydberg Atoms: High-Resolution Spectroscopy and Radiation Interaction—Rydberg Molecules

Dynamical localization in the microwave interaction of Rydberg atoms: The influence of noise

“…The packet of Rb atoms, of which every single atom saw exactly the same microwave pulse, is now traveling towards the field-ionization region. Here the atoms are ionized by an electric-field ramp [45] [1.8 V/(cm its)] and the ejected electrons are detected by a channeltron multiplier. The exact timing of laser excitation, microwave interaction, and field ionization is controlled by a pulse generator and delay lines such that, independently of their particular velocity, the atoms all interact for the same time not only with the microwave field, as men-…”

“…for all triplets (a,13,k)*(a',fl',1('), in which case only terms with (a,fl, k)= (a' , k' ) must be kept in (45). The master equation in the interaction picture then finally reads…”

Generation of photons on demand using cavity quantum electrodynamics

“…For three reasons these atoms are particularly suited for observing quantum effects in radiation-atom coupling. First, the states are very strongly coupled to the radiation field (the induced transition rates between neighboring levels scale as n 4 ); second, transitions are in the millimeter wave region, so that low-order mode cavities are large enough to allow rather long interaction times; finally, Rydberg states have relatively long lifetimes with respect to spontaneous decay [4,5]. The strong coupling of Rydberg states to radiation in resonance with transitions between neighboring levels can be understood in terms of the correspondence principle: with increasing n, the transition frequencies between neighboring levels approach the classical evolution frequency of the highly excited electron; therefore the atom can be considered as a large dipole oscillating at the transition frequency.…”
