标题： Finite entangling regions and information paradox in charged black holes

摘要： 本文研究了Reissner-Nordstrom黑洞的电荷对Hawking辐射精细熵动力学的影响，这些辐射被收集在有限纠缠区域内。我们证明，对于有限区域的某些尺寸，总可以选择一个电荷值，使得针对有限纠缠区域所提出的信息悖论不会出现。为了完整性起见，我们探讨了纠缠孤岛对此图景的影响。我们发现，在电荷值较小时，由于孤岛的消失导致熵出现间断，并且随着电荷增加，孤岛在整个演化过程中不再占据主导地位。 显示英文摘要

摘要： In this paper, we study the influence of the electric charge of Reissner-Nordstrom black hole on the dynamics of fine-grained entropy of Hawking radiation, collected in finite entangling regions. We demonstrate that for certain sizes of finite regions, it is always possible to choose a value of the charge such that no information paradox formulated for finite entangling regions arises. For the sake of completeness, we explore how entanglement islands influence the described picture. We find that at small values of the electric charge, there is a discontinuity in the entropy due to the disappearance of the island, and with increasing charge the island ceases to ever dominate throughout entire evolution.
