We investigated the quantum entanglement in spin-1 Heisenberg XY chain for two-spin-qutrit and multi-particle systems. As a measure of the entanglement, the negativity of this state was analyzed as a function of the temperature and the magnetic field. We gave some numerical results and discussed them in detail. We found that the negativity increases monotonously with the coupling constants |J1| and |J2|, and it showed a symmetry with respect to the point of J1=0 and J2=0. In addition to the above features, there is evidence that the critical temperature is independent of the length of the chain.

腹膜透析相关性腹膜炎是腹膜透析治疗的严重并发症,可导致多种不良临床结局。因此,预防及治疗腹膜透析相关性腹膜炎是改善患者预后的重要环节。临床上大多数腹膜透析相关性腹膜炎是由革兰氏阳性球菌引起的,青霉菌属较为罕见。本文报道1例45岁女性腹膜透析相关性腹膜炎患者,既往行电子结肠镜检查提示结直肠炎。入院后先后使用左氧氟沙星、亚胺培南西司他丁、氟康唑等抗感染治疗,后续腹膜透析管微生物培养结果提示青霉菌感染,予拔除腹膜透析管并使用伏立康唑抗真菌治疗后腹膜炎治愈。本例患者在诊治过程中发现其临床表现及常规实验室检查无特异性,对于治疗效果不佳或病原体培养阴性的腹膜炎患者,需警惕青霉菌感染的可能。在及时、规范治疗腹膜炎的同时应注意识别并处理腹膜透析相关性腹膜炎的易感因素。

We investigate the entanglement of the three-qubit Heisenberg XXX chain in the presence of impurity and obtain the analytical expressions of the concurrence C. It is found that for impurity entanglement, C appears only when J 1 > J for J > 0, and J 1 > 0 for J 0 and ?2J < J 1 < J, and initially increases with the increase of J 1 and arrives at the maximum value C max = (e4J/T ?3)/(e4J/T + 3) before it decays to zero gradually, so is the critical temperature T c with, however, the maximum value T cmax = 4J/In3.
