Black holes as generalised Toda molecules
Wissam Chemissany, Jan Rosseel, Thomas Van Riet
In this note we compare the geodesic formalism for spherically symmetric black hole solutions with the black hole effective potential approach. The geodesic formalism is beneficial…
Smeared versus localised sources in flux compactifications
Johan Blåbäck, Ulf H. Danielsson, Daniel Junghans +3
We investigate whether vacuum solutions in flux compactifications that are obtained with smeared sources (orientifolds or D-branes) still survive when the sources are localised. Th…
Black holes in supergravity and integrability
W. Chemissany, P. Fré, J. Rosseel +3
Stationary black holes of massless supergravity theories are described by certain geodesic curves on the target space that is obtained after dimensional reduction over time. When t…
Universal de Sitter solutions at tree-level
Ulf H. Danielsson, Paul Koerber, Thomas Van Riet
Type IIA string theory compactified on SU(3)-structure manifolds with orientifolds allows for classical de Sitter solutions in four dimensions. In this paper we investigate these s…
Lifshitz backgrounds from 10d supergravity
Johan Blåbäck, Ulf H. Danielsson, Thomas Van Riet
We investigate whether 4-dimensional static and cosmological Lifshitz solutions can be found from deforming the existing (A)dS_4 compactifications in IIA and IIA* supergravity. Usi…
