Time dependence of the atomic correlations for k₀r_a = 0.2, and k₀r_b = 0.6 (plot 1), 1.57 (plot 2), 3 (plot 3)

Figure 2. Time dependence of the atomic correlations for k₀r_a = 0.2, and k₀r_b = 0.6 (plot 1), 1.57 (plot 2), 3 (plot 3). Curves (a),(b) correspond to μ = Δ/Ω₀ = 0.05 and 0.01 respectively. The insert in figure 2(a) shows the case when the atoms are localized in equivalent anti-node positions at the distance k₀r = 2.7.

Abstract

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.
