源-陶布背景下的膜世界宇宙学
Braneworld cosmology in the sourced-Taub background
摘要：
提出了一种新的源-Taub背景下的膜世界。分别研究了内源区和外真空区的重力场方程。我们发现，尘埃膜的有效暗能量在源区的状态方程可以跨越幻影鸿沟$w=-1$。此外，在$H(z)$图上有一个下降，该图给出了$H(z)$最近直接数据的可能机制。
英文摘要：
A new braneworld in the sourced-Taub background is proposed. The gravity field equations in the internal source region and external vacuum region are investigated, respectively. We find that the equation of state for the effective dark energy of a dust brane in the source region can cross the phantom divide $w=-1$. Furthermore, there is a drop on $H(z)$ diagram, which presents a possible mechanism for the recent direct data of $H(z)$.
