微观处理德西特全息术

Micromanaging de Sitter holography

Xi Dong, Bart Horn, Eva Silverstein, Gonzalo Torroba

摘要:

我们开发工具,工程德西特真空与半全息的,使用椭圆纤维和orientifolds提升弗罗因鲁宾紧化与CFT的。对偶膜结构是紧凑的,构成了dS/dS对应的微观实现,将d维德西特空间实现为一个向下弯曲到(d-1)维德西特引力的扭曲紧化,耦合到一对大N物质扇区。这提供了一个参数的吉布斯-霍金熵的微观解释。我们说明了这些想法与一个明确的类的例子在三维空间,并描述正在进行的工作四维结构。

英文摘要:

We develop tools to engineer de Sitter vacua with semi-holographic duals, using elliptic fibrations and orientifolds to uplift Freund-Rubin compactifications with CFT duals. The dual brane construction is compact and constitutes a microscopic realization of the dS/dS correspondence, realizing d-dimensional de Sitter space as a warped compactification down to (d-1)-dimensional de Sitter gravity coupled to a pair of large-N matter sectors. This provides a parametric microscopic interpretation of the Gibbons-Hawking entropy. We illustrate these ideas with an explicit class of examples in three dimensions, and describe ongoing work on four-dimensional constructions.
