spectra, cubic couplings and the rigid fate of DGKT
Filippo Revello, Vincent Van Hemelryck
We show that in the DGKT scenario on a generic Calabi-Yau three-fold, a recently proposed holographic constraint on cubic couplings is satisfied if and only if the Calabi-Yau is ri…
Self-gravitating electromagnetic waves in the dark bubble model
Ulf Danielsson, Daniel Panizo, Vincent Van Hemelryck
We construct embeddings of gravitational and electromagnetic waves in the dark bubble scenario using pp-wave geometries in AdS5, motivated by the fact that pp-wave spacetimes often…
Broken and restored: a holographic constraint for AdS vacua with orbifolds
Filippo Revello, Vincent Van Hemelryck
It has been suggested that families of weakly-coupled AdS vacua with a large- holographic dual must satisfy non-trivial consistency requirements, which amount to the vanishing o…
Weak -manifolds and scale separation in M-theory from type IIA backgrounds
Vincent Van Hemelryck
This work provides evidence for the existence of supersymmetric and scale-separated AdS vacua in M-theory of the Freund-Rubin type. The internal space has weak -holonomy,…
