Wormholes in Horava gravity with cosmological constant

Understand

By combining analytical and numerical methods we find that the solutions of the complete Horava theory with negative cosmological constant that satisfy the conditions of staticity, spherical symmetry and vanishing of the shift function are two kinds of geometry: (i) a wormhole-like solution with two sides joined by a throat and (ii) a single side with a naked singularity at the origin.

• We study the second-order effective action.
• We consider the case when the coupling constant of the (partial ln N)^2 term, which is the unique deviation from general relativity in the effective action, is small.
• At one side the wormhole acquires a kind of deformed AdS asymptotia and at the other side there is an asymptotic essential singularity.
