论文摘要
我们研究了2 + 1个渐近抗DE保姆时空的平面黑洞微晶格的信息理论特性，该时空是由黑洞建模的，在地平线后面具有世界末日。双CFT中足够大的子区域的冯·诺伊曼（Von Neumann）的熵表现出一个时间依赖性阶段，从双向全外的角度来看，该阶段对应于brane描述中量子极端岛的出现。考虑到将DILATON重力添加到木板的情况下，我们表明调整相关的耦合会影响双CFT状态下信息的传播。通过在双重CFT中满足有关纠缠熵生长的信息理论界限，我们可以在brane上允许的耦合值范围。此外，我们通过展示如何使用对纠缠速度的跨度校正来启动Brane断层扫描的研究，以了解棕褐色的特性以及其本地化的任何引力动力学。
We study information theoretic properties of planar black hole microstates in 2 + 1 dimensional asymptotically anti-de Sitter spacetime, modeled by black holes with an end-of-the-world brane behind the horizon. The von Neumann entropy of sufficiently large subregions in the dual CFT exhibits a time-dependent phase, which from a doubly-holographic perspective corresponds to the appearance of quantum extremal islands in the brane description. Considering the case where dilaton gravity is added to the brane, we show that tuning the associated couplings affects the propagation of information in the dual CFT state. By requiring that information theoretic bounds on the growth of entanglement entropy are satisfied in the dual CFT, we can place bounds on the allowed values of the couplings on the brane. Furthermore, we initiate the study of brane tomography, by showing how subleading corrections to the entanglement velocity can be used to learn about the properties of the brane as well as any gravitational dynamics localized on it.
