Kerr-like phantom wormhole

Abstract: In this work we study a Kerr-like wormhole with phantom matter as source. It has three parameters: mass, angular momentum and scalar field charge. This wormhole has a naked ring singularity, other wise it is regular everywhere. The mean feature of this wormhole is that the mouth of the throat lie on a sphere of the same radius as the ring singularity an avoids any observer to see or to reach the singularity, it behaves like an anti-horizon. We analyse the geodesics of the wormhole and find that an observer can… Show more

“…The line element is roughly based on the axially symmetrical WH space-times (specifically the so-called ring WHs) found in [15,21], but with the element g tt of the inverse metric tensor modified so that the property ψ| q < 0 holds for any conserved quantity p i . Evidently, the construction of this metric is guided by geometrical arguments rather than physical significance.…”

“…While static-wormhole solutions appear unstable, models with spin and charge, such as Kerr-like wormholes (Miranda et al, 2013), have been calculated to be stable solutions. And furthermore link well with the expansion factor of spacetime generally referred to as 'dark energy', in that there may very well be a pervasive and ubiquitous field of negative energy that could support a Planckian wormhole spacetime architecture (keep in mind for instance that within the standard model the electron has infinite negative mass before vacuum renormalization).…”

“…Thus, metric (23) has a naked singularity at Δ = 0, which represents a ring on the equatorial plane centred in the centre of the wormhole 14 . If we drop out the acceleration a = 0, the rotation ω = 0, and metric (23) transforms into…”
