黑洞内部宇宙学的约束

Constraints on cosmologies inside black holes

Seamus Fallows, Simon F. Ross

摘要:

研究了Schwarzschild-AdS黑洞中常张力膜世界体积上封闭FRW宇宙学全息模型的构造。在d>2维中,具有膜不自相交的光滑欧几里德解将膜张力限制为T<T_*,阻止我们实现膜和体曲率尺度之间的尺度分离。我们表明,增加界面膜,这个模型并没有放松膜张力的条件。

英文摘要:

We study the construction of holographic models with closed FRW cosmologies on the worldvolume of a constant-tension brane inside a Schwarzschild-AdS black hole. In dimensions d>2, having a smooth Euclidean solution where the brane does not self-intersect limits the brane tension to T<T_*, preventing us from realising a separation of scales between the brane and bulk curvature scales. We show that adding interface branes to this model does not relax the condition on the brane tension.
