论文摘要
目前的工作调查了鹰辐射的纠缠熵，页面和争夺时间，用于全息轴心重力中永恒的平面黑洞。该解决方案对应于新的带电黑洞，因为由于大体中的轴突磁场诱导的重力质量，边界的差异损坏。这些黑洞解决方案的信息理论方面是在将岛屿规则应用于纠缠熵的情况下确定的。像非超级电荷的黑洞一样，辐射熵在No-Island构型中线性生长，而在岛屿配置中Bekenstein-Hawking熵设置的渐近值在近期饱和，边界位于外部地平线外。特别是，对于全息轴心重力的极端黑色平面，我们发现：（a）在岛屿不存在的早期，霍金辐射的纠缠熵不明显； （b）在后期，它趋向于独特的常数； （c）岛上的晚期位置确实是普遍的。此外，我们研究了页面时间如何受到全息重大重力变形的影响。对于小变形参数的中性溶液，对于具有几乎超级变形参数的带电溶液，我们发现页面转换发生在较早的时间。
The present work investigates the entanglement entropies of the Hawking radiations, the Page times, and the scrambling times, for the eternal planar black holes in the holographic axion gravity. The solutions correspond to a new class of charged black holes, because the boundary diffeomorphism is broken due to the graviton mass induced by the axion fields in the bulk. The information theoretical aspects of these black hole solutions is determined upon applying the island rule for the entanglement entropy. Like non-extremal charged black holes, the radiation entropy grows linearly in the no-island configurations, while is saturated at late times by asymptotic values set by the Bekenstein-Hawking entropy in the island configurations, with the boundary being located slightly outside the outer horizon. In particular, for the extremal black planes of holographic axion gravity, we find that: (a) the entanglement entropy of the Hawking radiation is ill-defined at the early times when the island is absent; (b) it tends to a distinctive constant at the late times; (c) the late-time location of the island is indeed universal. Moreover, we investigate how the Page time is affected by the holographic massive gravity deformation. For neutral solutions at the small deformation parameter, and for charged solutions with almost-extremal deformation parameter, we find that the Page transition happens at earlier times.
