Description
We investigate the dynamics of bipartite entanglement and nonclassical correlations in a dipole-dipole two-spin system subjected to the Dzyaloshinsky-Moriya (DM) interaction and the intrinsic decoherence. We consider that our system is initially prepared in a Werner state, and we study the effects of the intrinsic decoherence rate, the DM interaction, the dipolar coupling parameters and the intensities of the magnetic fields on the behaviors of the quantum correlations. We employ logarithmic negativity (ℒ𝒩) to quantify entanglement, whereas the nonclassical correlations are captured using the local quantum uncertainty (LQU) and the quantum discord (𝒬𝒟).
