通过AdS/CFT的间断永恒通货膨胀

Punctuated eternal inflation via AdS/CFT

David A. Lowe, Shubho Roy

摘要:

这项工作是试图在反德西特/共形场论(AdS/CFT)对偶性的框架内模拟暴胀的情景,AdS/CFT对偶性是通过弦论对量子引力的潜在完整的非微扰描述。我们期待在周围的史瓦西反德西特黑洞时空中的气泡几何与德西特内部,并获得在渐进AdS的边界上的对偶CFT中的状态的表征,其中代码的扩展dS泡。这些可以反过来用来指定宇宙学的初始条件。我们的方案很自然地将德西特空间的熵解释为黑洞微观态的状态子空间(的对数)。一致性检查和一些宇宙学的影响进行了讨论,包括如何克服的关键问题或传统的永恒的通货膨胀的悖论。

英文摘要:

The work is an attempt to model a scenario of inflation in the framework of Anti de Sit- ter/Conformal Field theory (AdS/CFT) duality, a potentially complete nonperturbative description of quantum gravity via string theory. We look at bubble geometries with de Sitter interiors within an ambient Schwarzschild anti-de Sitter black hole spacetime and obtain a characterization for the states in the dual CFT on boundary of the asymptotic AdS which code the expanding dS bubble. These can then in turn be used to specify initial conditions for cosmology. Our scenario naturally interprets the entropy of de Sitter space as a (logarithm of) subspace of states of the black hole microstates. Consistency checks are performed and a number of implications regarding cosmology are discussed including how the key problems or paradoxes of conventional eternal inflation are overcome.
