简并和临界畴壁以及由体粒子驱动的加速宇宙

Degenerate and critical domain walls and accelerating universes driven by bulk particles

A. de Souza Dutra, A. C. Amaro de Faria, M. Hott

摘要:

我们考虑这样一种情况,即我们的宇宙被视为嵌入在五维闵可夫斯基时空中的三维域壁,正如最初由Brito和合作者提出的那样[1]。我们探讨了存在的一个更丰富的类孤子的解决方案和它们的后果,为加速宇宙驱动的碰撞散装粒子激发与墙壁。特别是它表明,这些解决方案中的一些应该在整个扩展过程中发挥根本性的作用。

英文摘要:

We consider a scenario where our universe is taken as a three-dimensional domain wall embedded in a five-dimensional Minkowski space-time, as originally proposed by Brito and collaborators [1]. We explore the existence of a richer class of soliton solutions and their consequences for the acceleration of the universe driven by collisions of bulk particle excitations with the walls. In particular it is shown that some of these solutions should play a fundamental role throughout the expansion process.
