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 Cosmological Evolution With Bulk Matter
C. Bogdanos, K. Tamvakis
We consider the cosmological evolution of a brane for general bulk matter content. In our setup the bulk pressure and the energy exchange densities are comparable to the brane ener…
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…
Graviton Emission in the Bulk from a Higher-Dimensional Schwarzschild Black Hole
S. Creek, O. Efthimiou, P. Kanti +1
We consider the evaporation of (4+n)-dimensional non-rotating black holes into gravitons. We calculate the energy emission rate for gravitons in the bulk obtaining analytical solut…
