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…
Tachyonic de Sitter solutions of 10d type II supergravities
David Andriot
Cosmological models of the early or late universe exhibit (quasi) de Sitter space-times with different stability properties. Considering models derived from string theory, the swam…
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…
The web of swampland conjectures and the TCC bound
David Andriot, Niccolò Cribiori, David Erkinger
We consider the swampland distance and de Sitter conjectures, of respective order one parameters and . Inspired by the recent Trans-Planckian Censorship conjecture (TCC), we…
A new mechanism for symmetry breaking from nilmanifolds
David Andriot, Alan Cornell, Aldo Deandrea +2
We present a method to obtain a scalar potential at tree level from a pure gauge theory on nilmanifolds, a class of negatively-curved compact spaces, and discuss the spontaneous sy…
