论文摘要
在本文中，使用量子极限岛方法研究了低维高斯重力的信息悖论，称为三维EGB黑洞。为此，我们将一个辅助平浴系统连接到此临时奇异时空，并在重力较弱时估计其渐近区域中鹰辐射的熵。如图所示，将岛屿区域添加到纠缠的辐射楔中会导致其熵遵守页面曲线。量子极端表面或岛边界位于地平线外。这产生了与适当的页面曲线兼容的鹰辐射细粒熵的时间无关的方程式。我们还发现了此熵和页面时间的修改。
In this paper, the information paradox on lower-dimensional Gauss-Bonnet gravity known as a three-dimensional EGB black hole is studied using the quantum extremal island approach. For that, we connect an auxiliary flat bath system to this timelike singularity spacetime and estimate the entropy of hawking radiation in its asymptotic regions when gravity is weak. The addition of island areas to the entanglement wedge of radiation causes its entropy to obey the Page curve, as shown. The quantum extremal surface, or island boundary, is located outside the horizon. This yields a time-independent equation for Hawking radiation fine-grained entropy that is compatible with the appropriate Page curve. We also discover the modifications to this entropy and Page time.
