Supersymmetric scale-separated AdS orientifold vacua of type IIB
Vincent Van Hemelryck
I construct supersymmetric AdS vacua of type IIB string theory that exhibit parametric scale separation in the controlled regime. These solutions arise from compactifications o…

Charged Nariai black holes on the dark bubble
Ulf Danielsson, Vincent Van Hemelryck
In this paper, we realise the charged Nariai black hole on a braneworld from a nucleated bubble in AdS, known as the dark bubble model. Geometrically, the black hole takes the…

Connecting flux vacua through scalar field excursions
Gary Shiu, Flavio Tonioni, Vincent Van Hemelryck +1
We show how flux vacua that differ from each other in flux quanta can be seen as different vacua in a single scalar potential of an enlarged field space, which resolves the separat…
