拉伸额外的维度和泡沫的没有在一个玩具模型景观

Stretched extra dimensions and bubbles of nothing in a toy model landscape

I-Sheng Yang

摘要:

使用简单的6D结条件,我们描述了两个令人惊讶的几何形状。首先,在dS4xS2真空之间转变的情况下,S2可以被拉伸得显著大于转变之前和之后的真空值。然后,我们发现,天真的不稳定性,以解压缩实际上是一个泡沫的什么都没有。

英文摘要:

Using simple 6D junction conditions, we describe two surprising geometries. First in a case of transitions between dS4xS2 vacua, the S2 can be stretched significantly larger than the vacuum values both before and after the transition. Then we discover that the naive instability to decompactification is actually a bubble of nothing instead.
