伪真空随引力衰减中反弹解的存在性判据

Criteria of existence for bounce solutions in false vacuum decay with gravity

Nicholas W. K. Wong, Jiangbin Gong, Yen-Kheng Lim, Qing-hai Wang

摘要:

用半经典方法研究了与引力耦合的自相互作用标量场的反弹解。我们发现,反弹的解决方案有一个最大所需的障碍曲率,除了已知的最小所需的障碍曲率。特别是,作为最大障碍曲率接近,著名的Colemen-De Luccia(CDL)反弹解决方案的比例因子变得发散。与CDL或其更一般的振荡反弹对应物不同,这不能被认为是霍金-图罗克解的子集。

英文摘要:

The bounce solutions of self-interacting scalar fields coupled to gravity are studied using a semi-classical approach. We found that bounce solutions have a maximum required barrier curvature, in addition to the known minimum required barrier curvature. In particular, as the maximum barrier curvature is approached, the scale factor of the well-known Colemen-De Luccia (CDL) bounce solutions become divergent. Unlike the CDL or its more general oscillating bounce counterparts, this cannot be considered as a subset of the Hawking-Turok solution.
