Asymptotic entanglement versus dimensionless frequency ω0/γ for the Werner-like state with ε = 1, where ω1 = 90 γ, ω2 = 80γ, λ = 2γ, and γt = 50. Red lines correspond to γ1 = γ2 = γ and blue lines correspond to γ1 = γ, γ2 = 9γ. The upper solid lines correspond to the bilateral environment and the lower dash lines correspond to the unilateral environment.
