(a), (b) and (c) show the probabilities |t1|2, |t2|2, and the total probability |t1|2 + |t2|2, which correspond to the red dashed lines, blue solid lines, and black dashed dotted lines, respectively. (d) shows the probability . The blue solid line, red dashed line, and black dashed dotted line denote the situation as shown in (a), (b) and (c), respectively. For all the plots, the dissipation rate is taken and the coupling strengths Γ1 = 2Γ2. The respective parameters are (a) , , Δ1 = Δ2 = 0, (b) , , Δ2 = 5Γ2, Δ1 = Δ2 = 0, (c) , , Δ1 = Δ2 = −4Γ2.
