Kaluza-Klein紧化的新分支

New branch of Kaluza-Klein compactification

Shunichiro Kinoshita

摘要:

在Freund-Rubin型通量紧化中发现了一个新的解的分支。这些解决方案的几何形状被描述为外部空间具有德西特对称性和内部空间是拓扑球形。然而,它不是dS_p x S^q的简单形式,而是de Sitter空间和变形球的翘曲积。我们明确地构造了p=4和q=4的特定情况的数值解。我们证明了新的解分支来自dS_4 × S^4解分支中的边缘稳定解。

英文摘要:

We found a new branch of solutions in Freund-Rubin type flux compactifications. The geometry of these solutions is described as the external space which has a de Sitter symmetry and the internal space which is topologically spherical. However, it is not a simple form of dS_p x S^q but a warped product of de Sitter space and a deformed sphere. We explicitly constructed numerical solutions for a specific case with p=4 and q=4. We show that the new branch of solutions emanates from the marginally stable solution in the branch of dS_4 x S^4 solutions.
