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…
Axion-de Sitter wormholes
Sergio E. Aguilar-Gutierrez, Thomas Hertog, Rob Tielemans +2
We construct wormholes supported by axion flux in the presence of a positive cosmological constant. The solutions describe compact, one-handle bodies colloquially known as kettlebe…
Cosmic eggs to relax the cosmological constant
Thomas Hertog, Rob Tielemans, Thomas Van Riet
In theories with extra dimensions, the cosmological hierarchy problem can be thought of as the unnaturally large radius of the observable universe in Kaluza-Klein units. We sketch…
