Population versus (a) dimensionless time γ t, (b) relative decay rate γ₂/γ₁, and (c) spectral frequency ω₀/γ for the initial state given by Eq. (2) with c₁(0) = c₂(0) = 0 and c₃(0) = 1. The blue, red, and black lines correspond to populations P₁, P₂, and P₃, respectively. Other parameters are set as γ₁ = γ, λ = 2γ, ω₁ = 90 γ, and ω₂ = 80γ. (a) γ₂ = γ, ω₀ = 84γ; (b) γ t = 50, ω₀ = 85γ; (c) γ t = 50, γ₂ = γ (dash lines) or γ₂ = 9γ (solid lines).
