Non-exotic traversable wormholes in Einstein-Chern-Simons gravity
Mauricio Cataldo, Fernando Goméz, Paola Meza +2
We investigate traversable wormhole solutions in five-dimensional Einstein-Chern-Simons (EChS) gravity, a gauge-theoretic extension of General Relativity that introduces a higher-c…
Electromagnetically and gravitationally stealth fields
Cristian Quinzacara, Paola Meza, Almeira Sampson +1
We construct a generic class of models for complex scalar fields -- minimally coupled to gravity and electromagnetism -- with the property that their energy-momentum tensor and the…
Massive stealth scalar fields from field redefinition method
Cristian C. Quinzacara, Paola Meza, Almeira Sampson +1
We propose an uni-parametric deformation method of action principles of scalar fields coupled to gravity which generates new models with massive stealth field configurations, i.e.…
Phantom evolving wormholes with big rip singularities
Mauricio Cataldo, Paola Meza
We investigate a family of inhomogeneous and anisotropic gravitational fields exhibiting a future singularity at a finite value of the proper time. The studied spherically symmetri…
N-dimensional static and evolving Lorentzian wormholes with cosmological constant
Mauricio Cataldo, Paola Meza, Paul Minning
We present a family of static and evolving spherically symmetric Lorentzian wormhole solutions in N+1 dimensional Einstein gravity. In general, for static wormholes, we require tha…
