The Lorentzian Geometry of Tunneling in Global de Sitter at Late Time
Thibaut Coudarchet, Ben Freivogel, Bjoern Hassfeld +1
It is widely believed that Coleman--De Luccia (CDL) instantons characterize tunneling transitions in a de Sitter multiverse. Their most naive interpretation uses analytic continuat…
The String Theory Photoverse
Thibaut Coudarchet, Arthur Hebecker, Joerg Jaeckel +1
String theory compactifications come with numerous factors, implying the presence of many hidden photons in the low-energy EFT. One may call this the ``string photoverse''.…
Hiding the extra dimensions: A review on scale separation in string theory
Thibaut Coudarchet
We present an overview of both older and recent developments concerning scale separation in string theory. We focus on parametric scale separation obtained at the classical level i…
New families of scale separated vacua
Rafael Carrasco, Thibaut Coudarchet, Fernando Marchesano +1
Massive type IIA flux compactifications of the form AdS, where admits a Calabi-Yau metric and O6-planes wrapping three-cycles, display families of vacua with p…
Symmetric fluxes and small tadpoles
Thibaut Coudarchet, Fernando Marchesano, David Prieto +1
The analysis of type IIB flux vacua on warped Calabi--Yau orientifolds becomes considerably involved for a large number of complex structure fields. We however show that, for a qua…
Analytics of type IIB flux vacua and their mass spectra
Thibaut Coudarchet, Fernando Marchesano, David Prieto +1
We analyze the tree-level potential of type IIB flux compactifications in warped Calabi-Yau orientifolds, in regions of weak coupling and moderately large complex structure. In thi…
