利用复制方法计算了二体随机纯态模型的纠缠容量。我们找到了纠缠能力的精确表达式,它对有限维的希尔伯特空间是有效的。我们认为,在引力路径积分中,纠缠的能力只从对应于部分连通几何的次主导鞍点得到贡献。
We compute the capacity of entanglement in the bipartite random pure state model using the replica method. We find the exact expression of the capacity of entanglement which is valid for a finite dimension of the Hilbert space. We argue that in the gravitational path integral, the capacity of entanglement receives contributions only from the sub-leading saddle points corresponding to the partially connected geometries.
