遥平行引力中的膜世界建立和嵌入

Braneworld setup and embedding in teleparallel gravity

A. Behboodi, S. Akhshabi, K. Nozari

摘要:

我们构建了一个在远程平行引力五维braneworld场景的设置。研究了嵌入Anti de Sitter体中的Minkowski和Friedmann-Robertson-Walker膜的两种情况,并研究了有效的四维作用量. 4-维局部洛伦兹不变性被发现在这两种情况下恢复。然而,由于不同的结条件,四维宇宙演化方程不同于广义相对论情况。利用参考文献[13]的结果,我们考虑在这种情况下的一个简单的通货膨胀的情况。与广义相对论情形相比,暴胀参数被修正。

英文摘要:

We construct the setup of a five-dimensional braneworld scenario in teleparallel gravity. Both cases of Minkowski and Friedmann-Robertson-Walker branes embedded in Anti de Sitter bulk are studied and the effective 4-D action were studied. 4-dimensional local Lorentz invariance is found to be recovered in both cases. However, due to different junction conditions, the equations governing the 4-D cosmological evolution differ from general relativistic case. Using the results of Ref. [13], we consider a simple inflationary scenario in this setup. The inflation parameters are found to be modified compared to general relativistic case.
