论文摘要
计算真空衰减作用的隧道潜在方法是具有许多有吸引力特征的欧几里得弹跳方法的替代方法。在本文中，我们将形式主义扩展到一般的时空维度$ d> 2 $，并用它来提供几个结果的简单证明。对于Minkowski或Anti de Sitter False Vacua，我们表明重力或更高的屏障会增加真空寿命，并描述真空衰减的重力淬火的非常干净的图片。我们还得出了动作的薄壁限制，显示了DS与DS转换的详细平衡在新的形式主义中有效，以及如何获得可分析真空衰减溶液的电势。
The tunneling potential method to calculate the action for vacuum decay is an alternative to the Euclidean bounce method that has a number of attractive features. In this paper we extend the formalism to general spacetime dimension $d>2$ and use it to give simple proofs of several results. For Minkowski or Anti de Sitter false vacua, we show that gravity or higher barriers increase vacuum lifetime and describe a very clean picture of gravitational quenching of vacuum decay. We also derive the thin-wall limit of the action, show how detailed balance for dS to dS transitions works in the new formalism and how to obtain potentials for which the vacuum decay solution can be obtained analytically.
