暴胀和宇宙学常数

Inflation and the cosmological constant

F. R. Klinkhamer

摘要:

最近提出了一种特殊的补偿型解决方案的主要宇宙学常数的问题,两个无质量的矢量场动态抵消任意宇宙学常数Λ。天真的期望是,这种补偿机制不允许在非常早期的宇宙中存在暴胀阶段。然而,它表明,某些初始边界条件的向量场实际上可以引起一个暴胀阶段。

英文摘要:

A particular compensation-type solution of the main cosmological constant problem has been proposed recently, with two massless vector fields dynamically canceling an arbitrary cosmological constant Λ. The naive expectation is that such a compensation mechanism does not allow for the existence of an inflationary phase in the very early Universe. However, it is shown that certain initial boundary conditions on the vector fields can in fact give rise to an inflationary phase.
