论文摘要
我们提出了一个渐yan的欧几里得准备，该准备渐近广告$ _2 $时空，其中包含充气的ds $ _2 $泡泡。该设置可以用Minkowski真空和假真空嵌入四维理论中。广告$ _2 $ times 2-sphere近似于$ 4D $近距离RN虫洞的近地平线几何形状。同样，在虚假的真空中，近高级黑洞的近植物几何形状约为ds $ _2 $ times 2-Sphere。我们将欧几里得溶液解释为描述虫洞内部激发的衰变，以形成假真空气泡。结果是在不可转化的渐近minkowski虫洞内的充气区域。
We propose a Euclidean preparation of an asymptotically AdS$_2$ spacetime that contains an inflating dS$_2$ bubble. The setup can be embedded in a four dimensional theory with a Minkowski vacuum and a false vacuum. AdS$_2$ times 2-sphere approximate the near horizon geometry of a $4d$ near-extremal RN wormhole. Likewise, in the false vacuum the near-horizon geometry of a near-extremal black hole is approximately dS$_2$ times 2-sphere. We interpret the Euclidean solution as describing the decay of an excitation inside the wormhole to a false vacuum bubble. The result is an inflating region inside a non-traversable asymptotically Minkowski wormhole.
