Universal Cosmologies
Paul Marconnet, Dimitrios Tsimpis
Universal cosmologies are exact solutions of 10d type IIA supergravity containing a 4d Friedmann-Lemaître-Robertson-Walker factor, that can also be repackaged as solutions of 4d mo…
Universal accelerating cosmologies from 10d supergravity
Paul Marconnet, Dimitrios Tsimpis
We study 4d Friedmann-Lemaître-Robertson-Walker cosmologies obtained from time-dependent compactifications of Type IIA 10d supergravity on various classes of 6d manifolds (Calabi-Y…
Automated consistent truncations and stability of flux compactifications
David Andriot, Paul Marconnet, Muthusamy Rajaguru +1
Classical flux compactifications contribute to a well-controlled corner of the string landscape, therefore providing an important testing ground for a variety of conjectures. We fo…
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…
Warp factor and the gravitational wave spectrum
David Andriot, Paul Marconnet, Dimitrios Tsimpis
A distinct signature of compact extra dimensions would be a Kaluza-Klein tower of gravitational waves. Motivated by this prospect, we compute the corresponding spectrum on a warped…
Intricacies of classical de Sitter string backgrounds
David Andriot, Paul Marconnet, Timm Wrase
Up-to-date, there is no known example of a classical de Sitter solution of string theory, despite several good candidates. We consider here two newly discovered 10d supergravity de…
New de Sitter solutions of 10d type IIB supergravity
David Andriot, Paul Marconnet, Timm Wrase
We find and study 17 new de Sitter solutions of ten-dimensional (10d) type IIB supergravity with intersecting D5-branes and orientifold O5-planes, as well as a new Minkowski one. T…
