Coherence-induced entanglement
(American Physical Society, 2005)
We show how atomic coherence can lead to entanglement between two thermal fields at a temperature T. We first show that the passage of a three-level atom in V configuration without coherence cannot create entanglement. ...
Control of the Lamb shift by a driving field
(American Physical Society, 2010)
A unitary transformation approach is used to study the energy level shift of the atom coupled to both a vacuum electromagnetic field and a driving laser. The Lamb shift of the energy levels is shown to depend on the Rabi ...
