本文研究多体纠缠能否探测二分纠缠不可见的虫洞模量，在四边界AdS$_3$虫洞族中分析发现，沿对称线全局最小q=4多熵在参数范围内对扭转τ不敏感，直至二分RT熵开始敏感。
AI 中文摘要
我们提出一个问题：多体纠缠能否探测到对二分纠缠不可见的体模量？我们在一个由Fenchel-Nielsen扭转τ联系的四边界AdS$_3$虫洞显式族中研究此问题，询问完整的二分RT熵集合能否保持精确的τ无关性，而全息q=4多熵对扭转敏感。在我们分析的构型类中，对于足够小的|τ|，沿对称线ℓ=m我们未发现这样的区域：全局最小的q=4网络在整个分析的参数范围内本身是精确τ无关的。这一结论并非先验显然：它源于多个可允许构型之间的竞争，这些构型的相对排序随几何变化多次改变，并持续到二分RT熵本身变得对扭转敏感为止。
英文摘要
We ask whether multipartite entanglement can probe bulk moduli invisible to bipartite entanglement. We study this question in an explicit family of four-boundary AdS$_3$ wormholes related by a Fenchel-Nielsen twist $τ$, asking whether the complete set of bipartite RT entropies can remain exactly $τ$-independent while the holographic $\mathtt q=4$ multi-entropy is sensitive to the twist. Within the class of configurations analyzed here, for sufficiently small $|τ|$, we find no such regime along the symmetric line $\ell=m$: the globally minimal $\mathtt q=4$ network is itself exactly $τ$-independent throughout the parameter range analyzed. This conclusion is not a priori obvious: it emerges from a competition among several admissible configurations whose relative ordering changes multiple times as the geometry is varied, and persists up to the point where the bipartite RT entropies themselves become twist-sensitive.
