反弹塌陷模型的外部

Exteriors to bouncing collapse models

Tim Schmitz

摘要:

我们构建了一个大类的时空,顺利匹配均匀的,球对称的物质云。云的演化是任意的,以允许通过量子效应进行修改,这特别会导致反弹。我们进一步讨论了这些时空的两个简单但说明性的例子,无论是在一般情况下,并为一个特定形式的反弹,重点是视界行为和相关的时标。

英文摘要:

We construct a large class of spacetimes that are smoothly matched to homogeneous, spherically symmetric clouds of matter. The evolution of the clouds is left arbitrary to allow for the incorporation of modifications by quantum effects, which can in particular lead to bounces. We further discuss two simple yet illustrative examples of these spacetimes, both in general terms and for a specific form of the bounce, with a focus on horizon behavior and relevant timescales.
