Evolution of entanglement versus dimensionless time γ t for the Werner-like state with ε = 1 (dot-dash red lines), ε = 0.7 (solid black lines), and ε = 0.5 (dash blue lines): (a) bilateral environment case and (b) unilateral environment case. The parameters are chosen as γ1 = γ2 = γ, λ = 2γ, ω1 = 92γ, ω2 = 90γ, and ω0 = 91γ.
