Traversability of multi-boundary wormholes

We generalize the Gao-Jafferis-Wall construction of traversable two-sided wormholes to multi-boundary wormholes. In our construction, we take background spacetime be black holes in AdS$_3$. work hot limit where dual CFT state certain regions locally resembles thermofield double state. Furthermore, these regions, makes causal shadow exponentially small. Based on two features limit, and with three-boundary wormhole as main example, show that traversability between any asymptotic a can triggered using double-trace deformation. particular, boundary need not have same temperature angular momentum. discuss non-trivial dependence well effect region.
