论文摘要
在最近的一篇论文（ARXIV：1905.07348V1）中，戴森计划处理非富米汉尔顿剂的密度矩阵已被用来调查PT-对称性玻色子系统的纠缠状态。他们发现，冯·诺伊曼（Von Neumann）的熵可以在破碎和不间断的政权中显示出不同的行为。我们表明，它们的结果可以根据伪热矩阵的抽象模型进行重铸。但是发现，尽管形式主义实际上是相同的，但纠缠不是福克州，而是贝尔国家的。
In a recent paper (arXiv:1905.07348v1), Dyson scheme to deal with density matrix of non-Hermitian Hamiltonians has been used to investigate the entanglement of states of a PT-symmetric bosonic system. They found that von Neumann entropy can show a different behavior in the broken and unbroken regime. We show that their results can be recast in terms of an abstract model of pseudo-Hermitian random matrices. It is found however that, although the formalism is practically the same, the entanglement is not of Fock states but of Bell states.
