AdS/CMT的更多重力解

More gravity solutions of AdS/CMT

摘要:

我们将arXiv:0808.1725和arXiv:0808.3232中给出的引力解推广到具有标度对称性$r \to \f{r}λ, x_i \to λ^b x_i, t \to λ^a t$的任意甚至时空维。然而,对于$b=0$,我们有任意时空维的解,而不限于偶数维。选择$b$的物理意义是我们可以得到一个只有时间尺度不变性的解。从对偶场论的观点出发,讨论了与标量场对偶的算子的BF界和么正界。

英文摘要:

We have generalized the gravity solutions presented in arXiv:0808.1725 and arXiv:0808.3232 to arbitrary but even space time dimensions with the scaling symmetry $r \to \f{r}λ, x_i \to λ^b x_i, t \to λ^a t$. However, for $b=0$, we have the solution in arbitrary space time dimension, not restricted to even dimensional. The physical meaning of this particular choice of $b$ is that we can have a solution with only temporal scale invariance. From the dual field theory point of view, the BF bound and the unitarity bound for operators dual to scalar field is discussed.
