Traversable wormholes from massless conformally coupled scalar fields
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 wor...
متن کاملSelf-Similar Collapse of Conformally Coupled Scalar Fields
A massless scalar field minimally coupled to the gravitational field in a simplified spherical symmetry is discussed. It is shown that, in this case, the solution found by Roberts[1], describing a scalar field collapse, is in fact the most general one. Taking that solution as departure point, a study of the gravitational collapse for the self-similar conformal case is presented. Introduction Gr...
متن کاملOn the conformally coupled scalar field quantum cosmology
We propose a new initial condition for the homogeneous and isotropic quantum cosmology, where the source of the gravitational field is a conformally coupled scalar field, and the maximally symmetric hypersurfaces have positive curvature. After solving corresponding Wheeler-DeWitt equation, we obtain exact solutions in both classical and quantum levels. We propose appropriate initial condition f...
متن کاملBackreaction from non-zero mass conformally coupled scalar fields and the quantum creation of the Universe
The purpose of this paper is to study the homogeneous backreaction of nonzero mass conformally coupled scalar fields on a cosmological background, including flat spacetime, at one-loop order. For this study, the semiclassical Friedmann equation is solved using a method called order reduction. For a nearly flat background we get a scale factor that evolves to a stationary scale factor depending ...
متن کاملConformally Coupled Inflation
A massive scalar field in a curved spacetime can propagate along the light cone, a causal pathology, which can, in principle, be eliminated only if the scalar couples conformally to the Ricci curvature of spacetime. This property mandates conformal coupling for the field driving inflation in the early universe. During slow-roll inflation, this coupling can cause super-acceleration and, as a sig...
