Superluminal light propagation via quantum interference in decay channels
R. Arun
We examine the propagation of a weak probe light through a coherently driven -type system. Under the condition that the excited atomic levels decay via same vacuum modes, the ef…
Phase control of squeezing in fluorescence radiation
R. Arun
We study squeezing properties of the fluorescence radiation emitted by a driven -type atom in which the metastable lower energy levels are coupled by an additional field. We fin…
Interference-assisted squeezing in fluorescence radiation
R. Arun
The squeezing spectrum of the resonance fluorescence is studied for a coherently driven four-level atom in the Y-type configuration. It is found that the squeezing properties of th…
Atom Lithography with Near-Resonant Light Masks: Quantum Optimization Analysis
R. Arun, Offir Cohen, I. Sh. Averbukh
We study the optimal focusing of two-level atoms with a near resonant standing wave light, using both classical and quantum treatments of the problem. Operation of the focusing set…
Dark States and Interferences in Cascade Transitions of Ultra-Cold Atoms in a Cavity
R. Arun, G. S. Agarwal
We examine the competition among one- and two-photon processes in an ultra-cold, three-level atom undergoing cascade transitions as a result of its interaction with a bimodal cavit…
Tunneling and Traversal of Ultra-cold Atoms through Vacuum Induced Potentials
R. Arun, G. S. Agarwal
We examine the passage of ultra-cold two-level atoms through the potential produced by the vacuum of the cavity field. The peak of the transmitted wave packet generally occurs at t…
