Further refining the de Sitter swampland conjecture
David Andriot, Christoph Roupec
We propose an alternative refined de Sitter conjecture. It is given by a natural condition on a combination of the first and second derivatives of the scalar potential. We derive o…

Scaling limits of dS vacua and the swampland
Andreas Banlaki, Abhishek Chowdhury, Christoph Roupec +1
We discuss the properties of massive type IIA flux compactifications. In particular, we investigate in which case one can obtain dS vacua at large volume and small coupling. We sup…

de Sitter extrema and the swampland
Christoph Roupec, Timm Wrase
Recently it has been conjectured that string theory does not allow for dS vacua or dS extrema. To scrutinize such a conjecture, it is important to study concrete string theory comp…
