AdS_3的高自旋理论和引力排斥原理

Higher Spin Theories in AdS_3 and a Gravitational Exclusion Principle

Alejandra Castro, Arnaud Lepage-Jutier, Alexander Maloney

摘要:

本文考虑Anti-de Sitter空间中具有无质量高自旋规范对称性的三维量子引力理论。该理论的微扰谱包含了高自旋激发,它们可以被组织成W_N代数的真空表示,这些是边界引力子的高自旋版本。我们描述了一个基本界限,它将宇宙学常数的值与存在的规范对称性的量联系起来。在对偶CFT语言中,这是这样的陈述,即模不变性意味着理论不能被量化,除非中心荷足够大,即如果c大于或等于N-1。这个界限依赖于假设所有的微扰激发在量子理论中都以满态存在,并且如果理论具有线性化不稳定性,则可以绕过。W_N极小模型--最近被Gaberdiel和Gopakumar证明是某些高自旋AdS理论的对偶--提供了这种现象的一个例子。这个结果可以被视为反德西特空间中“引力不相容原理”的一个例子,在反德西特空间中,一个涉及黑洞的非微扰量子引力机制限制了光自由度的数量。

英文摘要:

We consider theories of three dimensional quantum gravity in Anti-de Sitter space which possess massless higher-spin gauge symmetry. The perturbative spectrum of the theory includes higher spin excitations which can be organized into vacuum representations of the W_N algebra; these are higher spin versions of the boundary gravitons. We describe a fundamental bound which relates the value of the cosmological constant to the amount of gauge symmetry present. In the dual CFT language, this is the statement that modular invariance implies that the theory can not be quantized unless the central charge is sufficiently large, i.e. if c is greater than or equal to N-1. This bound relies on the assumption that all of the perturbative excitations exist as full states in the quantum theory, and can be circumvented if the theory possesses a linearization instability. The W_N minimal models -- recently conjectured to be dual to certain higher spin AdS theories by Gaberdiel and Gopakumar - provide an example of this phenomenon. This result can be regarded as an example of a "gravitational exclusion principle" in Anti-de Sitter space, where a non-perturbative quantum gravity mechanism involving black holes places a limit on the number of light degrees of freedom present.
