Almost classical de Sitter?
Ludwig Horer, Daniel Junghans
The classical-dS scenario in the type II string theories proposes to search for dS vacua of orientifold flux compactifications in a regime where string corrections to the compactif…
Negative scalar potentials and the swampland: an Anti-Trans-Planckian Censorship Conjecture
David Andriot, Ludwig Horer, George Tringas
In this paper, we derive a characterisation of negative scalar potentials, , in -dimensional effective theories of quantum gravity. This is achieved thanks to an Anti-Trans…
(Quasi-) de Sitter solutions across dimensions and the TCC bound
David Andriot, Ludwig Horer
In this work, we investigate the existence of string theory solutions with a -dimensional (quasi-) de Sitter spacetime, for . Considering classical compactific…
Exploring the landscape of (anti-) de Sitter and Minkowski solutions: group manifolds, stability and scale separation
David Andriot, Ludwig Horer, Paul Marconnet
We classified in arXiv:2201.04152 certain 10d supergravity solutions with a 4d de Sitter, Minkowski or anti-de Sitter spacetime. We then found new solutions in previously unexplore…
Charting the landscape of (anti-) de Sitter and Minkowski solutions of 10d supergravities
David Andriot, Ludwig Horer, Paul Marconnet
We classify solutions of 10d type IIA/B supergravities with orientifolds, on a 4d maximally symmetric spacetime times a 6d group manifold. We then look for new solutions in previou…
