Figure 4. (a) The resonance fluorescence spectrum of two atoms for Δ = 0.1, Ω0 = 15 (dashed); Δ = 0.1, Ω0 = 18 (dotted); and Δ = 0.3, Ω0 = 40 (solid) (units of γ). (b) The second correlation function at τ = 0 for the whole localization regime of the atom b in the anti-node. In both figures we use γt = 0.1.
The resonance fluorescence emitted by two three-level atoms dressed in a strong laser field is studied. A stark dynamics shift based on photon statistics is discussed. The appearance of coherent Rabi oscillations (quantum beats) of the atoms located in the non-symmetric positions of the anti-nodes and the modification of the quantum correlations at the Stokes and anti-Stokes cooperative emission are described. For some positions of the atoms, we observed the violation of the Cauchy–Schwarz inequality, finding antibunching in the scattered light. We present a scheme to control the position of atoms dressed with the standing field via the resonance fluorescence.
