纠缠、混沌和复杂性对于德西特空间、AdS 和黑洞同样重要。 AdS和dS在这些概念在时空几何中的体现方式上既有相似之处,也有很大的不同。在本文的第一部分中,Ryu-Takayanagi 处方、快速置乱理论和全息复杂度对应关系针对德西特空间进行了重新表述。提出了描述德西特空间的全息模型的标准。这些标准可以概括为置乱和复杂性增长必须“超快”的要求。在本文的后面部分中,我证明了 SYK 的某个极限是德西特空间的具体的、可计算的全息模型。描述了支持该猜想的计算。
Entanglement, chaos, and complexity are as important for de Sitter space as for AdS and for black holes. There are similarities and great differences between AdS and dS in how these concepts are manifested in the space-time geometry. In the first part of this paper the Ryu-Takayanagi prescription, the theory of fast scrambling, and the holographic complexity correspondence are reformulated for de Sitter space. Criteria are proposed for a holographic model to describe de Sitter space. The criteria can be summarized by the requirement that scrambling and complexity growth must be"hyperfast."In the later part of the paper I show that a certain limit of SYK is a concrete, computable, holographic model of de Sitter space. Calculations are described which support the conjecture.
