标题： A Traversable Wormhole from the Kerr Black Hole

摘要： 高、贾法里斯和沃尓的方法通过对称黑洞背景摄动构造可穿越虫洞，在多个黑洞背景下取得了成功，尤其是BTZ和$AdS_2$，而历史上大多数虫洞解要么被发现违反非因果性的ANEC（平均能量条件），要么违反经典不可通过定理，要么仅存在于天文学上无关紧要的空间中。 在这项工作中，我们展示了Kerr近事件视界、近极值区域的双迹变形可以产生一个可穿越虫洞。我们还讨论了在渐近平坦空间中四维旋转可穿越虫洞的完全非微扰方法的可能性。 显示英文摘要

摘要： The approach of Gao, Jafferis, and Wall to perturbatively construct traversable wormholes has seen success in a number of black hole backgrounds, particularly BTZ and $AdS_2$, whereas historically most wormhole solutions have been either found to violate the achronal ANEC, violate a classical no-go theorem, or exist only in astrophysically irrelevant spacetimes. In this work, we show that a double-trace deformation to the near-horizon, near-extremal region of Kerr yields a traversable wormhole. We also comment on the potential for a fully nonperturbative approach to a four-dimensional rotating traversable wormhole in asymptotically flat space.
