Quantum correlation dynamics in a two-qubit Heisenberg XYZ model with decoherence*

With t → ∞, the steady concurrence and QD behaviors are plotted as a function of B [panels (a1) and (a2)] and Δ [panels (b1) and (b2)]. Other parameters are chosen as J = 1, γ = 1 and panels (a1) and (a2) for Δ = 0.5, panels (b1) and (b2) for B = 0.5.
