Time evolution of the quantum correlation calculated by C and QD. Panels (a1) and (a2) for different values of the uniform magnetic field B : B = 0.1 (solid line) and B = 0.9 (dotted line), respectively, with Δ = 0.5; panels (b1) and (b2) for different values of the anisotropic parameter Δ : Δ = 0.3 (solid line) and Δ = 0.8 (dotted line), respectively, with B = 0.5. Other parameters are J = 1 and γ = 1.
