通量紧化的自动一致截断和稳定性

Automated consistent truncations and stability of flux compactifications

David Andriot, Paul Marconnet, Muthusamy Rajaguru, Timm Wrase

摘要:

经典的通量紧致化有助于弦景观的一个良好控制的角落,因此提供了一个重要的试验场,为各种不同的结构。在这里,我们专注于II型超引力紧化的6d群流形向4d最大对称时空。我们开发了一个代码的截断左不变标量和降维到4D理论是自动的,任何可能的配置的OP-平面和DP-膜。然后,我们证明,任何这样的截断是一致的。我们进一步计算了质谱,并分析了许多de Sitter,Minkowski或anti-de Sitter解的稳定性,以及它们与沼泽地结构的一致性。

英文摘要:

Classical flux compactifications contribute to a well-controlled corner of the string landscape, therefore providing an important testing ground for a variety of conjectures. We focus here on type II supergravity compactifications on 6d group manifolds towards 4d maximally symmetric spacetimes. We develop a code where the truncation to left-invariant scalars and the dimensional reduction to a 4d theory are automated, for any possible configuration of Op-planes and Dp-branes. We then prove that any such truncation is consistent. We further compute the mass spectrum and analyse the stability of many de Sitter, Minkowski or anti-de Sitter solutions, as well as their consistency with swampland conjectures.
