论文摘要
在本文中，我们考虑了杂核复合物[Ni（dpt）（H2O）Cu（pbA）]。2H2O[PBA = 1,3-丙烯比（Oxamato）和DPT = BIS-（3-氨基丙基）胺通过混合旋转 - （1/2）COUPLEG的理论模型实现。我们根据希尔伯特·史密德（Hilbert-Schmidt Norm）和保真度研究了上述材料的热量子相关性的行为。我们观察到，量子相关度量以非常规的方式随着磁场而增加。系统参数的作用也在热平衡处提出。结果的亮点是，我们能够使用基于保真度的最小值来显示室温量子相关性的存在，而纠缠在141K处停止
In this article, we consider the heterodinuclear complex [Ni(dpt)(H2O)Cu(pba)].2H2O [pba =1,3-propylenebis(oxamato) and dpt = bis-(3-aminopropyl)amine] realized through the theoretical model of mixed spin-(1/2,1) coupled via Heisenberg interaction. We study the behaviors of thermal quantum correlations of the above material via Measurement-Induced Nonlocality (MIN) based on Hilbert-Schmidt norm and fidelity. We observe that the quantum correlation measures increase with the magnetic field in an unconventional way. The role of system parameters is also brought out at thermal equilibrium. The highlight of the results is that we are able to show the existence of room temperature quantum correlation using fidelity based MIN whereas the entanglement ceases to exist at 141K
