Dynamics of two-qubit quantum nonlocality in a Heisenberg chain model with the intrinsic decoherence

This paper investigates the dynamics of two-spin nonlocality generation in a Heisenberg XXX chain with Dzyaloshinskii-Moriya (DM) and Kaplan-Shekhtman-Entin-Wohlman-Aharony (KSEA) interactions. We analyze by using uncertainty-induced nonlocality, maximal Bell function, log-negativity. demonstrate that separable state, induced antiferromagnetic interaction as well x-component DM KSEA interactions, could evolve to state. The ability preserving can be enhanced increasing coupling strength spin-spin coupling. hierarchy principle is maintained for log-negativity entanglement. exhibits phenomena sudden death birth. sudden-death phenomenon due intrinsic decoherence, which also causes reduction nonlocality. While sudden-birth more robust, against than other types results indicate boosting interaction, produced (resulting from interactions) shielded decoherence effect.
