(color online) Time evaluation of the quantum correlations between two QDs mediated by MFs with quantum decoherence. The parameters are set as follows: tunneling coupling constant λ₁ = λ₂ = λ, QD energies ε_d1 = ε_d2 = 0, tunneling rate between the QDs and the leads Γ = 0.05, (a) ε_M = 0.5λ, (b) ε_M = 0. The insert show the details of the quantum discord in the interval t ∈ [0,8] in units of 1/λ.
