Relativistic quantum dynamics in strong fields: photon emission from heavy, few-electron ions

Recent progress in the study of the photon emission from highly charged heavy ions is reviewed. These investigations show that high-Z ions provide a unique tool for improving the understanding of the electron–electron and electron–photon interaction in the presence of strong fields. Apart from the bound-state transitions, which are accurately described in the framework of quantum electrodynamics, much information has also been obtained from the radiative capture of (quasi-) free electrons by high-Z ions. Many features in the observed spectra hereby confirm the inherently relativistic behaviour of even the simplest compound quantum systems in nature.

Generation of four-partite Greenberger-Horne-Zeilinger and W states by using a high-finesse bimodal cavity

We propose two schemes to engineer four-partite entangled Greenberger-Horne-Zeilinger (GHZ) and

states in a deterministic way by using chains of (two-level) Rydberg atoms within the framework of cavity QED. These schemes are based on the resonant interaction of the atoms with a bimodal cavity that simultaneously supports, in contrast to a single-mode cavity, two independent modes of the photon field. In addition, we suggest the schemes to reveal the nonclassical correlations for the engineered GHZ and
