论文摘要
我们讨论与真空衰减相关的粒子产生，该粒子的产生改变了诱导衰减的背景场耦合的标量场的质量。通过利用Stokes现象，我们可以最佳地跟踪模式函数的时间进化，从而正确计算粒子产生。特别是，我们将实时形式主义用于Minkowski和De Sitter时空的真空衰减以及Stokes现象方法。对于每种情况，我们分别考虑天桥真空衰减模型和随机通货膨胀。在实时形式主义中，可以将粒子的产生视为由非平凡的外部田地引起的。这使我们对真空衰减的实时形式主义有了新颖的看法。
We discuss particle production associated with vacuum decay, which changes the mass of a scalar field coupled to a background field which induces the decay. By utilizing the Stokes phenomenon, we can optimally track the time-evolution of mode function and hence calculate particle production properly. In particular, we use real time formalisms for vacuum decay in Minkowski and de Sitter spacetime together with the Stokes phenomenon method. For each case, we consider the flyover vacuum decay model and stochastic inflation, respectively. Within the real time formalism, the particle production can be viewed as that caused by nontrivial external fields. This gives us a novel perspective of the real time formalism of vacuum decay.
