AdS scale separation and the distance conjecture
Gary Shiu, Flavio Tonioni, Vincent Van Hemelryck +1
It has been argued that orientifold vacua with fluxes in type IIA string theory can achieve moduli stabilisation and arbitrary decoupling between the AdS and KK scales upon sending…
Over-extremal brane shells from string theory?
Ulf Danielsson, Vincent Van Hemelryck, Thomas Van Riet
We demonstrate that, if the usual phenomenological compactifications of IIB string theory with warped throats and anti-branes make sense, there must exist spherical brane shells in…
Axion wormholes with massive dilaton
Stefano Andriolo, Gary Shiu, Pablo Soler +1
If Euclidean wormholes contribute meaningfully to the path integral of quantum gravity they can have important implications for particle physics and cosmology. The dominant effects…
Comments on classical AdS flux vacua with scale separation
Fien Apers, Miguel Montero, Thomas Van Riet +1
AdS flux vacua with a parametric separation between the AdS and KK scales have been conjectured to be in the Swampland. We study flux compactifications of massive IIA supergravity…
Instantons and no wormholes in
D. Astesiano, D. Ruggeri, M. Trigiante +1
We study supergravity instantons sourced by axion (and saxion) fields in the Euclidean vacua of IIB supergravity. Such instantons are described by geo…
