Stability of Axion-Dilaton Wormholes
Caroline Jonas, George Lavrelashvili, Jean-Luc Lehners
We study the perturbative stability of Euclidean axion-dilaton wormholes that asymptotically approach flat space, both with a massless and a massive dilaton, and focussing on homog…

A Zoo of Axionic Wormholes
Caroline Jonas, George Lavrelashvili, Jean-Luc Lehners
As was discovered some time ago by Giddings and Strominger (GS), an axion can support a wormhole geometry in the presence of a massless dilaton, as long as the dilaton coupling rem…
