Type IIA on Spin(7) manifolds with fluxes
Niccolò Cribiori, Arda Hasar, Thomas Van Riet +1
We initiate a systematic study of compactifications of type II string theory to two dimensions on Ricci-flat spaces with fluxes and sources. We derive universal constraints on such…
A domain wall bound on anti-de Sitter vacua
Niccolò Cribiori, Antonia Paraskevopoulou, Thomas Van Riet
We consider anti-de Sitter flux vacua interpolated by flux-changing domain walls. Demanding that the tension of such a domain wall be above the ultraviolet cutoff of the effective…
A distance conjecture beyond moduli?
Cédric Debusschere, Flavio Tonioni, Thomas Van Riet
The distance conjecture states that for theories with moduli coupled to gravity a tower of states becomes light exponentially in the geodesic distance in moduli space. This specifi…
Stability of Axion-Saxion wormholes
T. Hertog, S. Maenaut, B. Missoni +2
We reconsider the perturbative stability of Euclidean axion wormholes. The quadratic action that governs linear perturbations is derived directly in Euclidean gravity. We demonstra…
