| dc.description | The thermal entanglement is investigated in a two-qubit Heisenberg XXZ system with Dzyaloshinskii–Moriya (DM) interaction. It is shown that the entanglement can be efficiently controlled by the DM interaction parameter and coupling coefficient J<sub>z</sub>. D<sub>x</sub> (the x-component parameter of the DM interaction) has a more remarkable influence on the entanglement and the critical temperature than D<sub>z</sub> (the z-component parameter of the DM interaction). Thus, by changing the DM interaction direction, we can get a more efficient control parameter to increase the entanglement and the critical temperature. |
