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…
