论文摘要
我们研究了[Arxiv：1908.10996]的双重全息模型，在这种情况下，二维JT重力理论中的黑洞在任意有限温度下与辅助浴系统耦合。根据黑洞的初始温度相对于浴温的温度，黑洞可能会通过排放鹰辐射，与浴室保持平衡或通过从浴缸中吸收热辐射来保持质量。在所有这些情况下，使用分析和数字计算，通过应用通常的全息纠缠熵处方来获得统一的页面曲线。随着纠缠楔重建的应用，我们进一步研究了包含鹰辐射的子系统的黑洞内部重建。我们检查了霍金辐射的作用以及在此重建中热浴的纯化。
We study the doubly holographic model of [arXiv:1908.10996] in the situation where a black hole in two-dimensional JT gravity theory is coupled to an auxiliary bath system at arbitrary finite temperature. Depending on the initial temperature of the black hole relative to the bath temperature, the black hole can lose mass by emitting Hawking radiation, stay in equilibrium with the bath or gain mass by absorbing thermal radiation from the bath. In all of these scenarios, a unitary Page curve is obtained by applying the usual prescription for holographic entanglement entropy and identifying the quantum extremal surface for the generalized entropy, using both analytical and numeric calculations. As the application of the entanglement wedge reconstruction, we further investigate the reconstruction of the black hole interior from a subsystem containing the Hawking radiation. We examine the roles of the Hawking radiation and also the purification of the thermal bath in this reconstruction.
