摘要:

在AdS长度之下的体物理的局域性是AdS/CFT对偶性的一个显著方面,也是最少被检验的方面之一。它要求AdS半径大于普朗克长度和弦的长度。在CFT中,这意味着一个大N展开和一个异常维度谱中的间隙。我们猜想,这一含义也运行在另一个方向,使任何CFT与平面扩展和一个大的差距有一个本地散装对偶。对于一个抽象的CFT,我们制定的一致性条件,最显着的交叉对称性,并表明该猜想是真实的,在广泛的CFT的,以1/N^2的第一个非平凡的顺序:任何CFT与间隙和平面扩展是通过AdS/CFT字典从本地批量相互作用。我们通过两边的计数参数建立了这个结果,并且还研究了一些显式解的各种性质。

英文摘要:

The locality of bulk physics at distances below the AdS length is one of the remarkable aspects of AdS/CFT duality, and one of the least tested. It requires that the AdS radius be large compared to the Planck length and the string length. In the CFT this implies a large-N expansion and a gap in the spectum of anomalous dimensions. We conjecture that the implication also runs in the other direction, so that any CFT with a planar expansion and a large gap has a local bulk dual. For an abstract CFT we formulate the consistency conditions, most notably crossing symmetry, and show that the conjecture is true in a broad range of CFT's, to first nontrivial order in 1/N^2: any CFT with a gap and a planar expansion is generated via the AdS/CFT dictionary from a local bulk interaction. We establish this result by a counting argument on each side, and also investigate various properties of some explicit solutions.
