On classical de Sitter solutions in higher dimensions
Thomas Van Riet
We derive necessary criteria for the existence of classical, meta-stable, de Sitter solutions in flux compactifications of type II supergravity down to dimensions higher than four.…
(Anti-)Brane backreaction beyond perturbation theory
Johan Blåbäck, Ulf H. Danielsson, Daniel Junghans +3
We improve on the understanding of the backreaction of anti-D6-branes in a flux background that is mutually BPS with D6-branes. This setup is analogous to the study of the backreac…
Einstein Branes
Wissam Chemissany, Bert Janssen, Thomas Van Riet
We generalise the standard, flat p-brane solutions sourced by a dilaton and a form field, by taking the worldvolume to be a curved Einstein space, such as (anti-)de Sitter space. O…
The problematic backreaction of SUSY-breaking branes
Johan Blåbäck, Ulf H. Danielsson, Daniel Junghans +3
In this paper we investigate the localisation of SUSY-breaking branes which, in the smeared approximation, support specific non-BPS vacua. We show, for a wide class of boundary con…
De Sitter hunting in a classical landscape
Ulf H. Danielsson, Sheikh S. Haque, Paul Koerber +3
We elaborate on the construction of de Sitter solutions from IIA orientifolds of SU(3)-structure manifolds that solve the 10-dimensional equations of motion at tree-level in the ap…
Brane solutions and integrability: a status report
W. Chemissany, P. Fré, J. Rosseel +3
We review the status of the integrability and solvability of the geodesics equations of motion on symmetric coset spaces that appear as sigma models of supergravity theories when r…
