Anti-brane singularities as red herrings
J. Blåbäck, F. F Gautason, A. Ruipérez +1
Unphysical 3-form flux singularities near anti-branes have been argued to get resolved in the classical supergravity regime when brane polarisation is properly taken into account.…
The two faces of T-branes
Iosif Bena, Johan Blåbäck, Raffaele Savelli +1
We establish a brane-brane duality connecting T-branes to collections of ordinary D-branes. T-branes are intrinsically non-Abelian brane configurations with worldvolume flux, where…
Constructing stable de Sitter in M-theory from higher curvature corrections
Johan Blåbäck, Ulf Danielsson, Giuseppe Dibitetto +1
We consider dimensional reductions of M-theory on with the inclusion of arbitrary metric flux and spacetime filling KK monopoles. With these ing…
Universal dS vacua in STU-models
J. Blåbäck, U. H. Danielsson, G. Dibitetto +1
Stable de Sitter solutions in minimal F-term supergravity are known to lie close to Minkowski critical points. We consider a class of STU-models arising from type IIB compactificat…
Power-law cosmologies in minimal and maximal gauged supergravity
J. Blåbäck, A. Borghese, S. S. Haque
In this paper we search for accelerating power-law solutions and ekpyrotic solutions within minimal and maximal four dimensional supergravity theories. We focus on the STU model fo…
