Second-order correlation versus delay time for γt = 0.1

Figure 3. Second-order correlation versus delay time for γt = 0.1. Figure (a) shows the total correlation function while (b)–(d) show Stokes, anti-Stokes and cross correlations. All curves correspond to atom a fixed in the point k₀r_a = 0.2, and k₀r_b is varied at various positions in the vicinity of the antinode.

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.
