论文摘要
我们使用双全息图的概念研究由永恒的BTZ黑洞在平衡中发出的鹰辐射，并以热浴为单位，但以扭曲的CFT $ _2 $ _2 $的自由度。与文献一致，我们发现纠缠岛和纠缠表面的相位过渡，但是我们的结果与在ADS/CFT中的工作有很大差异，以三种主要方式：（1）延迟时间的熵在时间上降低，（2）始终存在的自由度始终存在，而不仅是在较晚的情况下，无论是在较晚的情况下，都会涉及自由度的范围，并且（3都不在涉及到黑色的杂物（3）。发散，当边界间隔相对于黑洞的反度太大时，会出现。熵中的这种行为似乎与全息翘曲的CFT $ _2 $的非白血合性一致，并证明这些岛屿不是仅限于单一设置中黑洞信息的现象。
We use the notion of double holography to study Hawking radiation emitted by the eternal BTZ black hole in equilibrium with a thermal bath, but in the form of warped CFT$_2$ degrees of freedom. In agreement with the literature, we find entanglement islands and a phase transition in the entanglement surface, but our results differ significantly from work in AdS/CFT in three major ways: (1) the late-time entropy decreases in time, (2) island degrees of freedom exist at all times, and not just at late times, with the phase transition changing whether or not these degrees of freedom include the black hole interior, and (3) the physics involves a field-theoretic IR divergence, emerging when the boundary interval is too big relative to the black hole's inverse temperature. This behavior in the entropy appears to be consistent with the non-unitarity of holographic warped CFT$_2$ and demonstrates that the islands are not a phenomenon restricted to black hole information in unitary setups.
