Introduction to Cavity QED
This text arose in the course of the “Hauptseminar Experimentelle Quantenoptik” in WS 2010 at the TU Kaiserslautern, organized by Prof. Ott and Prof. Widera. I want to give a short introduction also from the theoretical point of view to the fascinating field of cavity quantum electrodynamics (CQED). Modern experiments (QND measurements on photons and photon blockade) are discussed and basic res...
متن کاملRaman Transitions in Cavity QED
In order to study quantum effects such as state superposition and entanglement, one would like to construct simple systems for which the damping rates are slow relative to the rate of coherent evolution. One such system is strong-coupling cavity quantum electrodynamics (QED), in which a single atom is coupled to a single mode of a high finesse optical cavity. In recent years, optical trapping t...
متن کاملIntensity correlations in cavity QED
The second-order intensity correlation function of light transmitted out of a cavity QED system exhibits the nonclassical features and dynamics of the atom-field interaction. We present measurements of the intensity correlation to examine the size of the nonclassical features and the dependence on driving intensity, detuning, and the strength of the atom-field coupling. We use a model that take...
متن کاملEffective QED actions: Representations, gauge invariance, anomalies, and mass expansions
We analyze and give explicit representations for the effective Abelian vector gauge field actions generated by charged fermions with particular attention to the thermal regime in odd dimensions, where spectral asymmetry can be present. We show, through z-function regularization, that both small and large gauge invariances are preserved at any temperature and for any number of fermions at the us...
متن کاملCavity QED with atomic mirrors
A promising approach to merge atomic systems with scalable photonics has emerged recently, which consists of trapping cold atoms near tapered nanofibers. Here, we describe a novel technique to achieve strong, coherent coupling between a single atom and photon in such a system. Our approach makes use of collective enhancement effects, which allow a lattice of atoms to form a high-finesse cavity ...
