标题： Wormhole influence on the false vacuum bubble tunneling

摘要： 在本研究中，我们将Farhi、Guth和Guven[核物理B 339 (1990) 417]的工作推广到包括虫洞效应。我们研究了虫洞对假真空气泡隧穿的影响。球对称的气泡有两个域壁。每个域壁的经典动力学受到两个经典禁止区域的限制。我们发现虫洞增加了瞬子的数量，从而可以增强隧穿率。我们解析地推导出了气泡隧穿率的公式，当虫洞消失时，该公式与Farhi、Guth和Guven的结果一致。我们表明隧穿率随着虫洞喉半径的增加而增加。此外，我们证明了隧穿率随着黑洞质量或表面张力的增加而增加。在气泡内存在虫洞并与另一个宇宙相连的情况下，我们演示了气泡可以通过量子隧穿进入另一个宇宙。 显示英文摘要

摘要： In this study, we generalize the work of Farhi, Guth and Guven [Nucl. Phys. B 339 (1990) 417] to include a wormhole effect. We study the influence of the wormhole on the tunneling of the false vacuum bubble. The spherically symmetric bubble has two domain walls. The classical dynamics of each domain wall are constrained by two classically forbidden regions. We find that the wormhole has increased the number of instantons and thus can enhance the tunneling rate. We have analytically derived the formula for the bubble tunneling rate, which is consistent with the result obtained by Farhi, Guth and Guven when the wormhole disappears. We show that the tunneling rate increases with the throat radius of the wormhole. Furthermore, we illustrate that the tunneling rate increases with an increases in the mass of the black hole or the surface tension. In the case where a wormhole exists within a bubble and is connected to another universe, we demonstrate that the bubble can enter into another universe through quantum tunneling.
