De Sitter Vacua from Non-perturbative Flux Compactifications
Johan Blåbäck, Diederik Roest, Ivonne Zavala
We present stable de Sitter solutions of supergravity in a geometric type IIB duality frame with the addition of non-perturbative contributions. Contrary to the s…
Superconformal Inflationary -Attractors
Renata Kallosh, Andrei Linde, Diederik Roest
Recently a broad class of superconformal inflationary models was found leading to a universal observational prediction and . Here we generalize this class of…
A universal attractor for inflation at strong coupling
Renata Kallosh, Andrei Linde, Diederik Roest
We introduce a novel non-minimal coupling between gravity and the inflaton sector. Remarkably, for large values of this coupling all models asymptote to a universal attractor. This…
Universality classes of inflation
Diederik Roest
We investigate all single-field, slow-roll inflationary models whose slow-roll parameters scale as 1/N in the limit of a large number of e-folds N. We proof that all such models be…
Kahler potentials for Planck inflation
Diederik Roest, Marco Scalisi, Ivonne Zavala
We assess which Kahler potentials in supergravity lead to viable single-field inflationary models that are consistent with Planck. We highlight the role of symmetries, such as shif…
Triality, Periodicity and Stability of SO(8) Gauged Supergravity
Andrea Borghese, Adolfo Guarino, Diederik Roest
While electromagnetic duality is a symmetry of many supergravity theories, this is not the case for the N=8 gauged theory. It was recently shown that this rotation leads to a one-p…
