De（Baby）Sitter重叠
De (Baby) Sitter Overlaps
摘要：
本文借用自旋玻璃理论的方法研究了膨胀宇宙中场的相空间结构。特别是，我们计算的重叠分布的一个适当的粗粒度，无质量标量的1+1维（因此婴儿）德西特背景，并发现（经过适当的移位和重新缩放），它是由一个Gumbel分布。我们还计算了该系统的三重重叠分布，其特征函数是两个Gumbel因子的乘积。
英文摘要：
In this note we employ methods borrowed from spin glass theory to study the phase space structure of fields in an inflating universe. In particular, we compute the overlap distribution of a suitably coarse-grained, massless scalar on a 1+1 dimensional (hence baby) de Sitter background, and find that (after an appropriate shift and rescaling) it is given by a Gumbel distribution. We also calculate the triple overlap distribution of this system, whose characteristic function turns out to be a product of two Gumbel factors.
