(a,b) Fidelity of the steady state \(|{{\rm{\Phi }}}_{1}^{0}\rangle \) versus gt with the initial state |Φ0〉. The chosen parameters are Ω1 = 0.037 g, Ω2 = 0.0775 g, and J = 20 g. In (a), the selected dissipative factors are γ = 0 and κ = 2.8 × 10−2  g. The inset of (a) shows the fidelity of the steady state as a function of the atomic spontaneous rate γ for the dissipative factors κ = 2.8 × 10−2  g. γ varies from 0 to 5 × 10−4  g at time 4 × 103/g. In (b), the selected dissipative factors are κ = 0 and γ = 2.72 × 10−4  g. The inset of (b) shows the fidelity of the steady state as a function of the cavity decay rate κ with the dissipative factor γ = 2.72 × 10−4  g. κ varies from 0 to 8 × 10−2  g at time 4 × 103/g.
