论文摘要
在弦乐理论中构建de Sitter真空的困难的动机，在Arxiv中提出了一种新方法：1807.01570和Arxiv：1907.04268，其中四个维度的空间被视为有效的宇宙学，是有效的宇宙学，随着物质和辐射的范围，在不断扩展的球体中，nontrable od decble $ sed $ nonsymmetrics $ susymmetric $ susymmetricricmmetricric $ $ ads_5 $在字符串理论中。在第三部分中，我们通过考虑散装物质和棕褐色的弯曲方式来进一步扩展这种情况。我们计算弯曲brane以及五个维数的反应度量。为了进一步阐明Brane弯曲的效果，我们将结果与使用全息处方的五维重力传播器进行了明确计算。最后，我们使用两个碰撞麸皮在模型中对四维重力的可能定位发表评论。
Motivated by the difficulty of constructing de Sitter vacua in string theory, a new approach was proposed in arXiv:1807.01570 and arXiv:1907.04268, where four dimensional de Sitter space was realized as the effective cosmology, with matter and radiation, on an expanding spherical bubble that mediates the decay of non supersymmetric $AdS_5$ to a more stable $AdS_5$ in string theory. In this third installment, we further expand on this scenario by considering the backreaction of matter in the bulk and on the brane in terms of how the brane bends. We compute the back reacted metric on the bent brane as well as in the five dimensional bulk. To further illuminate the effect of brane-bending, we compare our results with an explicit computation of the five dimensional graviton propagator using a holographic prescription. Finally we comment on a possible localization of four dimensional gravity in our model using two colliding branes.
