De Sitter空间中的纠缠

Entanglement in De Sitter Space

Edgar Shaghoulian, Leonard Susskind

摘要:

本文推广了最近提出的两个方案,\cite{Susskind:2021dfc} \cite{Susskind:2021esx}和\cite{Shaghoulian:2021cef},将Ryu-Takayanagi和Hubeny-Rangamani-Takayanagi公式推广到de Sitter空间.这两种方案(称为单层方案和双层方案)是相似的,都是用静态斑块的边界--换句话说,就是事件视界--来代替AdS的边界。在说明了每一种情况的规则之后,我们将它们应用于一些情况,并表明它们会产生基于其他理由的预期结果。单分子层和双分子层的提议通常给出相同的结果,但在一个特定的情况下,它们不一致。为了在它们之间做出明确的决定,我们需要更多地了解全息系统的热力学极限的本质。

英文摘要:

This paper expands on two recent proposals, \cite{Susskind:2021dfc}\cite{Susskind:2021esx} and \cite{Shaghoulian:2021cef}, for generalizing the Ryu-Takayanagi and Hubeny-Rangamani-Takayanagi formulas to de Sitter space. The proposals (called the monolayer and bilayer proposals) are similar; both replace the boundary of AdS by the boundaries of static-patches--in other words event horizons. After stating the rules for each, we apply them to a number of cases and show that they yield results expected on other grounds. The monolayer and bilayer proposals often give the same results, but in one particular situation they disagree. To definitively decide between them we need to understand more about the nature of the thermodynamic limit of holographic systems.
