论文摘要
我们研究了固定的De Sitter几何背景在假真空衰减的情况下的影响。目前可以理解，与一阶相变相关的气泡成核过程在宇宙学中尤为重要。时空的几何形状使对亚稳态真空的衰减速率的解释变得复杂。但是，在忽略反应的特定情况下，仍然可以研究曲率的效果。我们计算了位置空间中动作的虚构部分，包括一环和梯度校正。我们使用两种独立的方法，并量化校正的大小，而没有任何假设对标量背景配置的壁的厚度。
We study the effects of a fixed de Sitter geometry background in scenarios of false vacuum decay. It is currently understood that bubble nucleation processes associated with first order phase transitions are particularly important in cosmology. The geometry of spacetime complicates the interpretation of the decay rate of a metastable vacuum. However, the effects of curvature can still be studied in the particular case where backreaction is neglected. We compute the imaginary part of the action in de Sitter space, including the one-loop and the gradient corrections. We use two independent methodologies and quantify the size of the corrections without any assumptions on the thickness of the wall of the scalar background configuration.
