D维测井重力

D-Dimensional Log Gravity

Mohsen Alishahiha, Reza Fareghbal

摘要:

我们研究了在临界点处曲率平方修正的$D\geq 4$维中的爱因斯坦引力,其中理论只包含无质量引力子。我们表明,在临界点出现一个新的模式,导致对数引力理论。相应的对数解可以提供更高维度的对数CFT的重力描述。我们还注意到,对于理论参数的特殊值,该模型承认非相对论性等距的解决方案。

英文摘要:

We study Einstein gravity in dimensions $D\geq 4$ modified by curvature squared at critical point where the theory contains only massless gravitons. We show that at the critical point a new mode appears leading to a logarithmic gravity in the theory. The corresponding logarithmic solution may provide a gravity description of logarithmic CFT in higher dimensions. We note also that for special values of the parameters of the theory, the model admits solutions with non-relativistic isometries.
