真空体中双膜系统的宇宙学解

Cosmological solutions for a two-branes system in a vacuum bulk

Juan L. Perez, Miguel A. Garcia-Aspeitia, L. Arturo Urena-Lopez

摘要:

我们研究了五维时空中的两膜模型的宇宙学,其中额外坐标在轨道上被紧化。隐藏的膜充满了一个真正的标量场,它被赋予了二次势,表现为原始的暗物质场。这种情况下进行分析时,辐射效应是可以忽略不计的密度能量相比,所有可能的解决方案,通过动力系统的方法。

英文摘要:

We study the cosmology for a two branes model in a space-time of five dimensions where the extra coordinate is compactified on an orbifold. The hidden brane is filled with a real scalar field endowed with a quadratic potential that behaves as primordial dark matter field. This case is analyzed when the radion effects are negligible in comparison with the density energy; all possible solutions are found by means of a dynamical system approach.
