Morris -Thorne wormholes with a cosmological constant

First, the ideas introduced in the wormhole research field since the work of Morris and Thorne are reviewed, namely, the issues of energy conditions, wormhole construction, stability, time machines and astrophysical signatures. Then, spherically symmetric and static traversable Morris -Thorne wormholes in the presence of a generic cosmological constant Λ are analyzed. A matching of an interior ...

Wormholes and the Cosmological Constant*

We review Coleman’s wormhole mechanism for the vanishing of the cosmological constant. We show that in a minisuperspace model wormhole-connected universes dominate the path integral. We also provide evidence that the Euclidean path integral over geometries with spherical topology is unstable with respect to formation of infinitely many wormhole-connected 4-spheres. Consistency is restored by su...

Linearized stability analysis of thin-shell wormholes with a cosmological constant

Spherically symmetric thin-shell wormholes in the presence of a cosmological constant are constructed applying the cut-and-paste technique implemented by Visser. Using the Darmois-Israel formalism the surface stresses, which are concentrated at the wormhole throat, are determined. This construction allows one to apply a dynamical analysis to the throat, considering linearized radial perturbatio...

Exact geometric optics in a Morris-Thorne wormhole spacetime

The notion of a wormhole was first introduced in 1962 by John Wheeler [1] who reinterpreted the Einstein-Rosen bridge [2] as a connection between two distant places in spacetime with no mutual interaction. However, he realized together with Robert Fuller [3] that this Schwarzschild wormhole cannot be traversed even by a single particle. In 1988, Michael Morris and Kip Thorne [4] presented the m...

Wormholes in spacetimes with cosmological horizons

A generalisation of the asymptotic wormhole boundary condition for the case of spacetimes with a cosmological horizon is proposed. In particular, we consider de Sitter spacetime with small cosmological constant. The wave functions selected by this proposal are exponentially damped in WKB approximation when the scale factor is large but still much smaller than the horizon size. In addition, they...
