We show that toroidal compactification of type II string theory to six dimensions admits axionic euclidean wormhole solutions. These wormholes can be inserted into AdS3 × S3 × T4 backgrounds, which have a well-defined CFT dual. AdS/CFT duality then suggests that the wormhole solutions cannot be interpreted using α parameters as originally suggested by Coleman.

Solving the simplest theory of quantum gravity (2012, background): “This casts doubts on the argument [38] that higher dimensional wormholes should be unphysical saddle points, based on the observation that Euclidean wormholes exist in the bulk in certain AdS/CFT setups while the CFT knows nothing about them.”
Planckian axions and the Weak Gravity Conjecture (2015, methodology): “2 arise in the low-energy effective theories arising from string theory, which generally include additional fields, such as the dilaton — see [12].”
Late Time Correlation Functions, Baby Universes, and ETH in JT Gravity (2019, background): “The mechanism behind the non-decaying behavior of these correlation functions is topology change due to Euclidean wormholes [31, 32, 33, 34, 35, 36, 37, 38, 39], which also accounted for the non-decaying behavior of the spectral form factor in [14, 29].”
Fencing in the swampland: quantum gravity constraints on large field inflation (2015, background): “In [33], it was found that constructing a certain class of Euclidean worm-holes required one to have large axionic field ranges.”
Sharpening the weak gravity conjecture with dimensional reduction (2015, background): “Of these possibilities, the wormhole case has received the most attention [17, 45–50], as it is the only example that is smooth and non-trivial.”
A semiclassical ramp in SYK and in gravity (2018, background): “Several of our colleagues have emphasized to us that this is reminiscent of the situation with Euclidean wormholes [49, 50, 51], for which the correct AdS/CFT interpretation remains unclear.”
Transcending the ensemble: baby universes, spacetime wormholes, and the order and disorder of black hole information (2020, background): “The presence of spacetime wormholes in the path integral now leads to a phenomenon which is very puzzling from the standard AdS/CFT point of view [58, 63] (see [55, 56] for earlier discussions of the asymptotically flat analogue in which Smatrix elements play the role of our partition functions).”
