论文摘要
最近的论文1809.01197描述了全息CFT的状态如何通过大量非相互作用的BCFT的状态近似，从而使新系统的双重偶的偶尔准确地近似于原始几何的任意因果斑块。在本文中，我们首先要详细描述这种离散的BCFT系统的几何形状，并强调它们是多边界虫洞，在不同的渐近区域之间不可能在因果关系中移动。通过以各种方式重新引入BCFT之间的耦合，我们表明虫洞可以使蠕虫遍布，从而提供了中间类别的几何形状，这些几何形状在多边界虫洞与其近似的原始几何形状之间插值。
The recent paper 1809.01197 described how states of a holographic CFT can be approximated by states of a large collection of non-interacting BCFTs, such that the dual of the new system accurately approximates an arbitrarily large causal patch of the original geometry. In this paper, we first describe in more detail the geometries dual to such discrete BCFT systems, emphasizing that they are multi-boundary wormholes in which it is not possible to move causally between different asymptotic regions. By reintroducing couplings between the BCFTs in various ways, we show that the wormholes can be made traversable, giving an intermediate class of geometries that interpolate between the multi-boundary wormhole and the original geometry that it approximates.
