Traversable wormholes from massless conformally coupled scalar fields
نویسندگان
چکیده
The massless conformally coupled scalar field is characterized by the so-called ‘‘new improved stress-energy tensor’’, which is capable of classically violating the null energy condition. When coupled to Einstein gravity we find a three-parameter class of exact solutions. These exact solutions include the Schwarzschild geometry, assorted naked singularities, and a large class of traversable wormholes. q 1999 Elsevier Science B.V. All rights reserved.

متن کامل0 Scalar fields , energy conditions , and traversable wormholes
We describe the different possibilities that a simple and apparently quite harmless classical scalar field theory provides to violate the energy conditions. We demonstrate that a non-minimally coupled scalar field with a positive curvature coupling ξ > 0 can easily violate all the standard energy conditions, up to and including the averaged null energy condition (ANEC). Indeed this violation of...

متن کاملConformal Continuations and Wormhole Instability in Scalar-tensor Gravity
We study the stability of static, spherically symmetric, traversable wormholes existing due to conformal continuations in a class of scalar-tensor theories with zero scalar field potential (so that Fisher’s well-known scalar-vacuum solution holds in the Einstein conformal frame). Specific examples of such wormholes are those with nonminimally (e.g., conformally) coupled scalar fields. All bound...
متن کاملElectrically Charged and Neutral Wormhole Instability in Scalar-tensor Gravity
We study the stability of static, spherically symmetric, traversable wormholes with or without an electric charge, existing due to conformal continuations in a class of scalar-tensor theories with zero scalar field potential (so that Penney’s or Fisher’s well-known solutions hold in the Einstein conformal frame). Specific examples of such wormholes are those with nonminimally (e.g., conformally...
