Flux Compactifications, dS Vacua and the Swampland
Christoph Roupec
One of the main goals of the field of string phenomenology is to describe the properties of our spacetime in low-energy effective models related to and consistent with string theor…
Non-supersymmetric branes
Niccolò Cribiori, Christoph Roupec, Magnus Tournoy +2
We discuss how to incorporate non-supersymmetric branes in compactifications of type II string theories. We particularly focus on flux compactifications on stru…
Constructing the Supersymmetric anti-D3-brane action in KKLT
Niccolò Cribiori
The derivation of the complete anti-D3-brane low energy effective action in KKLT is reviewed. All worldvolume fields are included, together with the background moduli. The result i…
de Sitter Minima from M theory and String theory
Niccolò Cribiori, Renata Kallosh, Andrei Linde +1
We study M-theory compactification on in the presence of a seven-flux, metric fluxes and KK monopoles. The effective four-dimensional supergravity…
Mass Production of IIA and IIB dS Vacua
Niccolò Cribiori, Renata Kallosh, Andrei Linde +1
We describe several applications of the recently proposed mass production procedure, where multiple moduli are stabilized in a dS vacuum, in supergravity models inspired by string…
Uplifting Anti-D6-brane
Niccolò Cribiori, Renata Kallosh, Christoph Roupec +1
A simple, KKLT-like construction of de Sitter vacua in type IIA string theory is presented in an STU model with guidance from string theory U-duality and with an uplifting anti-D6-…
The supersymmetric anti-D3-brane action in KKLT
Niccolò Cribiori, Christoph Roupec, Timm Wrase +1
An anti-D3-brane plays a crucial role in the construction of semi-realistic cosmological models in string theory. Part of its action provides an uplift term that has been used to l…
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…
