AI 中文摘要
我们在引力侧建立了一个自下而上的模型，用于研究“潜在的”德西特/界面共形场论（dS/ICFT）对应关系，采用Coleman-De Luccia瞬子。通过膜吸收暴胀子剧烈变化的区域后，时空由两个半径不同的德西特时空组成，二者通过膜连接；若dS/CFT猜想正确，该时空预期对偶于一个界面共形场论。我们的目标是分析现有全息伪熵计算方案（即此类时空中的极值曲面），论证其中部分方案会与界面共形场论普适性质的预期结果产生悖论，并在解析延拓后将我们的结果与反德西特/界面共形场论对应关系（AdS/ICFT）的结果进行比较。我们还从与界面垂直的子区域相关的纠缠熵中提取g函数。
英文摘要
We establish a bottom-up model for studying the `would-be' de-Sitter/interface CFT (dS/ICFT) correspondence on the gravity side, using the Coleman-De Luccia instanton. After absorbing the region where the inflaton changes dramatically by a brane, the spacetime consists of two de Sitter spacetimes with different radii joined by a brane, which is expected to be dual to an interface CFT provided that the dS/CFT conjecture is correct. Our goal is to analyze existing prescriptions for the holographic computation of pseudo-entropy, i.e. the extremal surface in such a spacetime and argue that some of them would cause parodox with the results expected the universal properties of interface CFT and compare our results with that of Anti de Sitter/interface CFT correspondence (AdS/ICFT) after analytic continuation. We also read off the $g$-function from the entanglement entropy associated with a subregion perpendicular to the interface.
