研究了均匀磁场中Dzialoshinski-Moriya （DM）相互作用对双量子位XXZ自旋链热纠缠的影响。发现DM相互作用可以增强热纠缠。当D足够大时，在更大的温度和强磁场下可以存在纠缠态。
The effect of Dzialoshinski–Moriya (DM) interaction on thermal entanglement of a two-qubit XXZ spin chain in a homogenous magnetic field is investigated. It is found that the DM interaction can enhance thermal entanglement. When D is large enough, the entanglement can exist for larger temperatures and strong magnetic field.
