多杂质对均匀磁场下各向异性海森堡环XXZ纠缠的影响

Multi-impurity effects on the entanglement of anisotropic Heisenberg ring XXZ under a homogeneous magnetic field

Gao Wen Bin, Yang Guo Hui, Zhou Ling

摘要:

研究了均匀磁场中多杂质对各向异性海森堡环XXZ纠缠度的影响。杂质使环中相等的两两纠缠相互竞争,使两两纠缠出现振荡。如果杂质具有较大的耦合,则临界温度和两两纠缠度都可以得到改善

英文摘要:

The effects of multi-impurity on the entanglement of anisotropic Heisenberg ring XXZ under a homogeneous magnetic field have been studied. The impurities make the equal pairwise entanglement in a ring compete with each other so that the pairwise entanglement exhibits oscillation. If the impurities are of larger couplings, both the critical temperature and pairwise entanglement can be improved
