Figure 3

Different kinds of correlations as a function of λ+ (initial state coefficient) in the case of coherent evolution, at a fixed value of relative phase =ω0τ set to π/4. Due to the periodic behaviour of the correlations as a function of observed in Fig. 2a, the results are immediately applicable, for example, at the point =3π/4 that is in the region of first revival. The black solid line, dashed red line, dot-dashed blue line and dotted dark cyan line represent, respectively, the theoretical predictions of total , classical , quantum correlations and concurrence C (the value is set to 0 when Γ<0, which is represented by the solid dark cyan line). Black, red, blue and dark cyan dots represent the corresponding experimental results. Error bars are due to the counting statistics. There is a good agreement among theoretical curves and experimental points.
