我们考虑了dS/CFT对应中的纠缠熵。在德西特时空上的爱因斯坦引力中,我们提出了全息纠缠熵作为欧几里得反德西特时空极值表面的解析延拓。尽管爱因斯坦引力在德西特时空上的对偶共形场理论还不知道,我们分析了与瓦西里耶夫的高自旋规范理论对偶的自由模型作为一个玩具模型。在这个模型中,我们确认了类似于爱因斯坦引力全息结果的行为。
We consider the entanglement entropy in the dS/CFT correspondence. In Einstein gravity on de Sitter spacetime we propose the holographic entanglement entropy as the analytic continuation of the extremal surface in Euclidean anti–de Sitter spacetime. Even though dual conformal field theories for Einstein gravity on de Sitter spacetime are not known yet, we analyze the freemodel dual to Vasiliev’s higher spin gauge theory as a toy model. In this model we confirm the behavior similar to our holographic result from Einstein gravity.
