The emission intensity I (a) and Mandel's Q parameter (b) versus time t . The red lines represent the emission intensity and Mandel's Q parameter of the parallel system and the black lines represent that of the orthogonal system. The solid lines correspond to the 𝓦 12 = 𝓦 13 = 0 and the dashed lines correspond the 𝓦 12 = 𝓦 13 = 𝓦 23 = Γ . The average Rabi frequencies are Ω 12 = Ω 13 = 20 Γ , the detuning frequency is Δ = 2.5 Γ , and the system is in the ground state.
