Toward eternal traversable hairy wormholes

We aim to build stable and reasonably natural traversable wormhole solutions. We show that conventional semiclassical matter in the bulk cannot support a Poincare-symmetric wormhole. Then we construct stable semiclassical hairy wormhole solutions where the hair violates the Poincare invariance. Finally, we argue that stringy effects make wormhole pair production generic (in fact, not ending up with wormholes requires fine tuning). We also discuss the Kolmogorov-Sinai entropy of the wormhole hair, compare it to the Bekenstein-Hawking entropy and discuss the thermodynamic stablity of the wormhole solutions.
