We study the process of quantum tunnelling in self-interacting scalar field theories with non-minimal coupling to gravity. In these theories gravitational instantons can develop a neck -- a feature prohibited in theories with minimal coupling, and describing the nucleation of geometries containing a wormhole. We also clarify the relationship of neck geometries to violations of the null energy condition.

Wormhole Nucleation via Topological Surgery in Lorentzian Geometry
Wormhole nucleation is achieved via 0-surgery yielding a singular cobordism, resolved by connected sum with CP² to produce a nonsingular Lorentzian metric with closed timelike curves and violated energy conditions.
