A new source for a braneworld cosmological constant from a modified gravity model in the bulk
Orfeu Bertolami, Carla Carvalho, Joao Laia
We show that a four-dimensional equation of state for a cosmological constant term arises from a perfect fluid in the bulk in the context of a gravity model where the scalar curvat…

Non-minimal coupling as a mechanism for spontaneous symmetry breaking on the brane
Orfeu Bertolami, Carla Carvalho
Motivated by the dimensional asymmetry characteristic of braneworlds, we populate the bulk spacetime with matter scalar fields, both real and complex, and couple them non-minimally…

Spontaneous Symmetry Breaking in the Bulk as a Localization Mechanism of Fields on the Brane
Orfeu Bertolami, Carla Carvalho
We consider real and complex scalar fields non-minimally coupled to gravity in the bulk spacetime and study their impact on the brane upon acquiring a non-vanishing vacuum expectat…
