Abstract:
Quantum correlations in a two-qubit anisotropic Heisenberg XXZ system with Dzyaloshinskii-Moriya (DM) couplings in a homogenous magnetic field are analysed. Dependence of quantum discord (QD) and concurrence (C) of the system on spin and DM anisotropies is studied. Results presented here are in good agreement with conclusions obtained for similar models.
