Quantum correlation dynamics in a two-qubit Heisenberg XYZ model with decoherence |
Time evolution of the quantum correlation calculated by C and QD. Panels (a1) and (a2) for different values of the anisotropic parameter b : b = 0.1 (solid line) and b = 0.8 (dotted line), respectively, with Δ = 0.5; panels (b1) and (b2) show different values of the anisotropic parameter Δ : Δ = 0.1 (solid line) and Δ = 0.8 (dotted line), respectively, with b = 0.5. Other parameters are: C 1 = 0.9, C 2 = 0.6, C 3 = 0.3, J = 1, γ = 1, and B = 0.5. |
