Control schemes for collective resonance fluorescence — •Mihai Macovei, Jörg Evers, and Christoph H. Keitel — Max-Planck Institute for Nuclear Physics, Saupfercheckweg 1, D-69117 Heidelberg, Germany.

0.3cm Multi-atom systems [1] have received considerable attention due to their possible applications in various fields of modern quantum optics. For any applications, however, convenient control parameters to influence the collective atomic dynamics are required [2]. We shall show then various schemes to manipulate the quantum properties of a collection of dipole-interacting few-level atoms. In particular, both the steady-state collective populations and the spectral features of these samples can be controlled by varying the laser parameters, temperature of the environmental bath or especially the atomic-level spacings by, e.g., static magnetic fields. 0.5cm [1] R.
