de Sitter流与Anti de Sitter流和(超)重力景观

de Sitter versus Anti de Sitter flows and the (super)gravity landscape

Elias Kiritsis, Alexander Tsouros

摘要:

研究了爱因斯坦标量引力中的一般解,该解可以在de Sitter和Anti-de Sitter区域之间插值。首先将\cite{exotic}正则解的分类推广到dS区域。这意味着,除其他外,宇宙时钟的存在,扭转方向,而不通过曲率奇点。然后,我们考虑的解决方案,dS和AdS制度之间的插值的ananterior。这种更一般的解决方案和他们的奇异性的结构进行了研究。它表明,有没有正规的解决方案,dS和AdS极值之间的插值一般潜力。这与半人马座的解决方案不同,半人马座的解决方案被证明存在于两个体积维度中。我们还评论了潜在的相互作用与最近的dS的结构和dS BF界限。

英文摘要:

Generic solutions are studied in Einstein-scalar gravity in an ansatz that can interpolate between de Sitter and Anti-de Sitter regimes. The classification of regular solutions of \cite{exotic} is first extended to the dS regime. This implies, among others, the existence of cosmic clocks that reverse direction without passing through a curvature singularity. We then consider an ansatz for solutions that interpolate between the dS and AdS regimes. The structure of such more general solutions and their singularities are studied. It is shown that there are no regular solutions that interpolate between dS and AdS extrema for generic potentials. This is unlike the Centaur solutions that were shown to exist in two bulk dimensions. We also comment on the potential interplay with recent dS conjectures and the dS BF bounds.
