Intrinsic decoherence effects on nonclassical correlations in a symmetric spin–orbit model

Abdel‐Baset A. Mohamed, Ahmad N. Khedr, Saeed Haddadi +3 more

Nonclassical correlations dynamics of local quantum Fisher information, trace-norm measurement-induced nonlocality, and log-negativity are investigated in a symmetric spin–orbit model. This model is described by a Heisenberg XYZ two-spin system exposed to the magnetic field and Kaplan–Shekhtman–Entin-Wohlman–Aharony (KSEA) interaction under the intrinsic decoherence effects. To evaluate the resourcefulness of this model for the generation and preservation of quantum correlations, we consider two qubits that are initially prepared in two different states, namely uncorrelated and maximally correlated states. The magnetic field is discovered to be effective at generating and preserving nonclassical correlations. Besides, we find that the KSEA interaction can alter the generation, preservation, and revival features of nonclassical correlations in the two-qubit system. However, the bipartite nonclassical correlations become extremely fragile when intrinsic decoherence effects appear.

Thermal entanglement in a two-qubit HeisenbergXYchain with the Dzyaloshinskii–Moriya interaction

Qin Meng, Xu Sheng-Long, Tao Ying-Juan +1 more

This paper investigates thermal entanglements of a two-qubit Heisenberg XY chain in the presence of the Dzyaloshinskii–Moriya anisotropic antisymmetric interaction. By the concept of concurrence, it is found that the effects of spin–orbit coupling on the entanglement are different from those of spin–spin model. The analytical expressions of concurrence are obtained for this model.
