Localization of atomic ensembles via superfluorescence
M. Macovei, J. Evers, C. H. Keitel +1
The sub-wavelength localization of an ensemble of atoms concentrated to a small volume in space is investigated. The localization relies on the interaction of the ensemble with a s…
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…
Quantum tunneling through vacuum-multiparticle induced potentials
Mihai A. Macovei
The vacuum cavity mode induces a potential barrier and a well when an ultra-slow excited atom enters the interaction region so that it can be reflected or transmitted with a certai…
Light propagation through closed-loop atomic media beyond the multiphoton resonance condition
Mohammad Mahmoudi, Joerg Evers
The light propagation of a probe field pulse in a four-level double-lambda type system driven by laser fields that form a closed interaction loop is studied. Due to the finite freq…
Photoionization Broadening of the 1S-2S Transition in a Beam of Atomic Hydrogen
N. Kolachevsky, M. Haas, U. D. Jentschura +7
We consider the excitation dynamics of the two-photon \sts transition in a beam of atomic hydrogen by 243 nm laser radiation. Specifically, we study the impact of ionization dampin…
Strong-field spatial interference in a tailored electromagnetic bath
M. Macovei, J. Evers, G. -x. Li +1
Light scattered by a regular structure of atoms can exhibit interference signatures, similar to the classical double-slit. These first-order interferences, however, vanish for stro…
Collective coherent population trapping in a thermal field
M. Macovei, Z. Ficek, C. H. Keitel
We analyzed the efficiency of coherent population trapping (CPT) in a superposition of the ground states of three-level atoms under the influence of the decoherence process induced…
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…
