Axion Wormholes in AdS Compactifications

We find regular axionic Euclidean wormhole solutions in Type IIB string theory compactified on ${\text{AdS}}_5\times {\text{S}}^5\mathrm{/}{\mathbb{Z}}_k$. AdS/CFT enables a precise derivation of the axion content of the Euclidean theory, placing the string theory embedding of the wormholes on firm footing. This further sharpens the paradox posed by these solutions.
