论文摘要
我们在浴缸中以有限的温度在有限的温度下获得了由共形场理论描述的双分部分混合状态的全息纠缠负性，偶的构型涉及涉及在Braneworld几何形状中的两个交流黑洞的构型。在这种情况下，我们分析了以黑洞之间的信息传递为特征的混合状态纠缠结构。该模型对应于在脑植物几何形状中对二维永恒JT黑洞的配置，涉及两个通过$ CFT_2 $ s描述的共享浴系统耦合的Planck Branes。我们的结果重现了在随机矩阵理论和JT黑洞构型中的几何蒸发背景下获得的页面曲线的类似物。
We obtain the holographic entanglement negativity for bipartite mixed states at a finite temperature in baths described by conformal field theories dual to configurations involving two communicating black holes in a braneworld geometry. In this context, we analyze the mixed state entanglement structure characterized by the information transfer between the black holes. The model corresponds to a configuration of two dimensional eternal JT black holes in a braneworld geometry involving two Planck branes coupled through shared bath systems described by $CFT_2$s. Our results reproduce analogue of the Page curves for the entanglement negativity obtained earlier in the context of random matrix theory and from geometric evaporation in JT black hole configurations.
