论文摘要
我们通过在两个边界理论之间添加一个耦合，从一个带电的广告黑洞中构建一个可穿越的虫洞。我们研究了这种变形的效果在黑洞的极端极限中的作用。黑洞具有有限的熵，但在极端极限处无限地喉咙。我们认为，即使在极限限制下，仍然可以使喉咙横穿，但这需要调整我们添加接近不稳定性阈值的边界耦合或与温度偶然缩放的强度。在后一种情况下，我们表明可以通过熵通过虫洞尺度发送的信息量。
We construct a traversable wormhole from a charged AdS black hole by adding a coupling between the two boundary theories. We investigate how the effect of this deformation behaves in the extremal limit of the black hole. The black holes have finite entropy but an infinitely long throat in the extremal limit. We argue that it is still possible to make the throat traversable even in the extremal limit, but this requires either tuning the field for which we add a boundary coupling close to an instability threshold or scaling the strength of the coupling inversely with the temperature. In the latter case we show that the amount of information that can be sent through the wormhole scales with the entropy.
