关于新的大质量引力和AdS/CFT

On the new massive gravity and AdS/CFT

Aninda Sinha

摘要:

要求存在一个简单的全息$c$ -定理,它表明,一般(宇称保持)引力理论在2+1维涉及多达四个导数曲率不变减少到新的大规模引力理论。我们考虑扩展的理论,包括多达六个衍生曲率不变量。给出了黑洞解,并检验了与1+1 CFTs的一致性.我们提出的证据表明,散装酉性仍然是在冲突与一个积极的CFT中心荷一般的参数选择。然而,对于出现在四阶和六阶导数项中的参数的特殊选择,将线性化方程减少为二阶导数,从而改善了么正性问题。

英文摘要:

Demanding the existence of a simple holographic $c$-theorem, it is shown that a general (parity preserving) theory of gravity in 2+1 dimensions involving upto four derivative curvature invariants reduces to the new massive gravity theory. We consider extending the theory including upto six derivative curvature invariants. Black hole solutions are presented and consistency with 1+1 CFTs is checked. We present evidence that bulk unitarity is still in conflict with a positive CFT central charge for generic choice of parameters. However, for a special choice of parameters appearing in the four and six derivative terms reduces the linearized equations to be two derivative, thereby ameliorating the unitarity problem.
