Wormholes in 2d Horava-Lifshitz quantum gravity

We quantize the two-dimensional projectable Horava-Lifshitz gravity with a bi-local as well as spacelike wormhole interaction. The resulting quantum Hamiltonian coincides with the one obtained through summing over all genus in the string field theory for two-dimensional causal dynamical triangulations. This implies that our wormhole interaction can be interpreted as a splitting or joining interaction of one-dimensional strings. (C) 2021 The Author(s). Published by Elsevier B.V.

Automated summary

By quantizing the two-dimensional projectable Horava-Lifshitz gravity with bi-local and spacelike wormhole interaction, we find that the resulting quantum Hamiltonian coincides with that obtained through summing over all genus in the string field theory, implying that the wormhole interaction can be interpreted as a splitting or joining interaction of one-dimensional strings.
