Tunnelling for Large N

Yun-Song Piao

摘要:

在这篇简短的笔记中,通过将随机方法应用于多个场,我们估计了具有$\cal N$场的景观中真空之间隧穿的概率。我们发现,概率可以提高大$\cal N$。当$\cal N$使某个真空的dS熵饱和时,相应的真空将非常不稳定,并且预计会迅速衰减。我们讨论了这一结果的影响。

英文摘要:

In this brief note, by applying the stochastic approach to multiple fields, we estimate the probability of tunneling between vacua in a landscape with $\cal N$ fields. We find that the probability can be enhanced by large $\cal N$. When $\cal N$ saturates the dS entropy of some vacuum, the corresponding vacuum will be extremely unstable and be expected to rapidly decay. We discuss the implications of this result.
