中文摘要：
研究了各向异性和Dzyaloshinski-Moriya相互作用对（1/2,1）混合自旋海森堡XXZ模型热纠缠的影响.结果表明,通过调节各向异性参数Δ以及Dzyaloshinski-Moriya相互作用的大小,可以很好地控制系统的纠缠度和临界温度,因此可以得到一个有效的控制参数来提高纠缠度和扩大纠缠稳定值的范围来降低纠缠的减小程度.
英文摘要：
Thermal entanglement of a（1/2,1） mixed-spin Heisenberg XXZ model in the presence of Dzyaloshinski-Moriya（DM） interaction and anisotropy Δ is investigated.It is shown that the thermal entanglement and the critical temperature can be efficiently controlled by adjusting the DM interaction parameter and anisotropy coefficient Δ.Thus,by changing the values of DM interaction and anisotropy coefficient Δ,we can get a more efficient control parameter to increase the entanglement and expand the steady value region to slow down the decreace of the entanglement.
