BPS domain walls from backreacted orientifolds
Johan Blåbäck, Bert Janssen, Thomas Van Riet +1
Compactifications with D-brane and orientifold sources lead to standard gauged supergravity theories if the sources are smeared over the internal directions. It is therefore of int…
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…
Accelerated Universes from type IIA Compactifications
Johan Blåbäck, Ulf Danielsson, Giuseppe Dibitetto
We study slow-roll accelerating cosmologies arising from geometric compactifications of type IIA string theory on . With the aid of…
A note on M2-branes in opposite charge
Johan Blåbäck
The flux singularity that arise when branes are put in an oppositely charged background is a wildly discussed issue and in this paper the problem is investigated further. New AdS w…
Fully stable dS vacua from generalised fluxes
Johan Blåbäck, Ulf Danielsson, Giuseppe Dibitetto
We investigate the possible existence of (meta-)stable de Sitter vacua within N=1 compactifications with generalised fluxes. With the aid of an algorithm inspired by the method of…
