标题： Universality of holographic entanglement properties in holographic QCD

摘要： 我们在这项工作中研究全息QCD模型中纠缠性质的模型依赖性。 我们考虑了两个有代表性的全息QCD模型，并检验了各种纠缠度量，包括纠缠熵、条件互信息和纯化纠缠。 我们的分析涉及比较这两个模型中这些纠缠性质的行为。 我们观察到，使用直接UV截断重整化方法得到的纠缠熵，对所使用的具体模型表现出显著的依赖性。 然而，其他非发散的纠缠度量，如与截断无关的纠缠熵、条件互信息和纯化纠缠，在数值坐标和标准坐标中都表现出模型无关的特性。 此外，我们在临界终点（CEP）和一阶相变中观察到了纠缠性质的不同相变行为，在两种坐标中均如此。 然而，在数值坐标和标准坐标之间，纠缠性质的行为存在显著差异。 显示英文摘要

摘要： We study the model dependence of entanglement properties in holographic QCD models in this work. We considered two representative holographic QCD models and examined various entanglement measures, including entanglement entropy, conditional mutual information, and entanglement of purification. Our analysis involved comparing the behaviors of these entanglement properties between the two models. We observed that the entanglement entropy obtained using the direct UV-cutoff renormalization method, showed significant dependence on the specific model used. However, other non-divergent entanglement measures, such as cutoff-independent entanglement entropy, conditional mutual information, and entanglement of purification, displayed model-independent properties in both numerical coordinates and standard coordinates. Additionally, we observed distinct phase transition behaviors of entanglement properties at the critical end point (CEP) and first-order phase transitions in both coordinates. Nonetheless, there were significant differences in the behavior of entanglement properties between numerical coordinates and standard coordinates.
