Braneworld solutions from scalar field in bimetric theory
arXiv:1210.6318 · doi:10.1103/PhysRevD.87.065007
Abstract
We investigate the presence of braneworld solutions in a bimetric theory, with gravity and the scalar field coupling differently. We consider a non-standard model, with a Cuscuton-like scalar field, and we show how to generate braneworld solutions in this new scenario. In particular, we found no gravitational instabilities for the braneworld solutions.
