Synergistic Gravity and the Role of Resonances in GRS-Inspired Braneworlds
C. Bogdanos, A. Dimitriadis, K. Tamvakis
We consider 5D braneworld models of quasi-localized gravity in which 4D gravity is reproduced at intermediate scales while the extra dimension opens up at both the very short and t…
Brane Cosmology with a Non-Minimally Coupled Bulk-Scalar Field
C. Bogdanos, A. Dimitriadis, K. Tamvakis
We consider the cosmological evolution of a brane in the presence of a bulk scalar field coupled to the Ricci scalar through a term f(ϕ)R. We derive the generalized Friedmann equat…
Dark energy from bulk matter
C. Bogdanos, A. Dimitriadis, K. Tamvakis
We consider the possibility of getting accelerated expansion and w=-1 crossing in the context of a braneworld cosmological setup, endowed with a bulk energy-momentum tensor. For a…
Brane Models with a Ricci-Coupled Scalar Field
C. Bogdanos, A. Dimitriadis, K. Tamvakis
We consider the problem of a scalar field, non-minimally coupled to gravity through a term, in the presence of a Brane. Exact solutions, for a wide range of values of th…
Enhancon Solutions: Pushing Supergravity to its Limits
Apostolos Dimitriadis, Amanda W. Peet, Geoff Potvin +1
We extend the investigation of nonextremal enhancons, finding the most general solutions with the correct symmetry and charges. There are two families of solutions. One of these co…
Properties of non-extremal enhancons
Apostolos Dimitriadis, Simon F. Ross
We study the supergravity solutions describing non-extremal enhancons. There are two branches of solutions: a `shell branch' connected to the extremal solution, and a `horizon bran…
