从AdS零解和宇宙学解得到的Lifshitz时空

Lifshitz spacetimes from AdS null and cosmological solutions

Koushik Balasubramanian, K. Narayan

摘要:

本文描述了具有$z=2$ Lifshitz对称标量场的$AdS_5\times S^5$零变形的10维超引力解。3+1维的大体积Lifshitz几何由这些解的降维而产生。在这种情况下,对偶场论是N=4的超级杨-米尔斯理论的变形。本文讨论了与体标量对偶的算子的全息二点函数。我们进一步描述了时间相关的(宇宙)的解决方案,具有各向异性的Lifshitz标度对称性。我们还讨论了$AdS\times X$在11维超引力中的形变,这与上面的解有些类似。在这里的某些情况下,我们期望场论是陈-西蒙斯理论在以奇点堆叠的M2-膜上的变形。

英文摘要:

We describe solutions of 10-dimensional supergravity comprising null deformations of $AdS_5\times S^5$ with a scalar field, which have $z=2$ Lifshitz symmetries. The bulk Lifshitz geometry in 3+1-dimensions arises by dimensional reduction of these solutions. The dual field theory in this case is a deformation of the N=4 super Yang-Mills theory. We discuss the holographic 2-point function of operators dual to bulk scalars. We further describe time-dependent (cosmological) solutions which have anisotropic Lifshitz scaling symmetries. We also discuss deformations of $AdS\times X$ in 11-dimensional supergravity, which are somewhat similar to the solutions above. In some cases here, we expect the field theory duals to be deformations of the Chern-Simons theories on M2-branes stacked at singularities.
