Two-mode single-atom laser as a source of entangled light
M. Kiffner, M. S. Zubairy, J. Evers +1
A two-mode single-atom laser is considered, with the aim of generating entanglement in macroscopic light. Two transitions in the four-level gain medium atom independently interact…
Coherent control in a decoherence-free subspace of a collective multi-level system
M. Kiffner, J. Evers, C. H. Keitel
Decoherence-free subspaces (DFS) in systems of dipole-dipole interacting multi-level atoms are investigated theoretically. It is shown that the collective state space of two dipole…
Breakdown of the few-level approximation in collective systems
M. Kiffner, J. Evers, C. H. Keitel
The validity of the few-level approximation in dipole-dipole interacting collective systems is discussed. As example system, we study the archetype case of two dipole-dipole intera…
Interference in the resonance fluorescence of two incoherently coupled transitions
Martin Kiffner, Joerg Evers, Christoph H. Keitel
The fluorescence light emitted by a 4-level system in to configuration driven by a monochromatic laser field and in an external magnetic field is studied. We show t…
Detection of atomic entanglement and electromagnetically induced transparency in velocity-selective coherent population trapping
M. Kiffner, K. -P. Marzlin
We investigate theoretically the optical properties of an atomic gas which has been cooled by the laser cooling method velocity-selective coherent population trapping. We demonstra…
