摘要:

在本文中,我们分析了二维全息CFT真空态中多部分纠缠度量在体全息对称性的问题。我们首先定义了一类多部分局域幺不变量,即多重不变量,它们具有给定的全息对称性,该对称性在复制体上自由且传递地作用。我们寻找这样一个度量子类,使得对偶的体几何也能保持全息对称性。如果我们要求体对于区域的一般构型保持全息对称性,我们得到了该问题最一般的解。用全息对称性对体解进行轨道化,得到一个带有锥形奇点网络的体几何。我们的方法清楚地表明,存在无穷多个无限大的多重不变量家族,使得每个家族在全息态上求值相同。在几何上,这些是涉及体体积的等式,可能在模空间中的特定点处具有可能不同的亏格。在某些情况下,我们用CFT中的显式计算来检验我们的体计算。最后,我们评论了向更高维度的推广。

英文摘要:

In this paper, we analyze the question of replica symmetry in the bulk for multi-partite entanglement measures in the vacuum state of two dimensional holographic CFTs. We first define a class of multi-partite local unitary invariants, multi-invariants, with a given replica symmetry that acts freely and transitively on the replicas. We look for a subclass of measures such that the dual bulk geometry also preserves replica symmetry. We obtain the most general solution to this problem if we require the bulk to preserve replica symmetry for general configurations of the regions. Orbifolding the bulk solution with the replica symmetry gives us a bulk geometry with a network of conical singularities. Our approach makes it clear that there are infinitely many infinitely large families of multi-invariants such that each family evaluates identically on the holographic state. Geometrically, these are equalities involving volumes of handlebodies, possibly of different genus, at particular points in the moduli space. In certain cases, we check our bulk computation with an explicit calculation in CFT. Finally we comment on the generalization to higher dimension.
