具有非最小耦合的伪真空泡动力学

Dynamics of false vacuum bubbles with nonminimal coupling

Bum-Hoon Lee, Chul H. Lee, Wonwoo Lee, Siyoung Nam, Chanyong Park

摘要:

我们研究了假真空泡的动力学。非最小耦合标量场引起负张力效应。从外部观察者的角度来看,假真空泡的质量可以是正的、零的或负的。内部假真空具有德西特几何,而外部真真空背景可以具有取决于真空能量的几何。我们证明了在没有初始奇点的情况下,存在膨胀的假真空泡。

英文摘要:

We study the dynamics of false vacuum bubbles. A nonminimally coupled scalar field gives rise to the effect of negative tension. The mass of a false vacuum bubble from outside observer's point of view can be positive, zero, or negative. The interior false vacuum has de Sitter geometry, while the exterior true vacuum background can have geometry depending on the vacuum energy. We show that there exist expanding false vacuum bubbles without the initial singularity in the past.
