Gauss - Bonnet brane cosmology
We consider 5-dimensional spacetimes of constant 3-dimensional spatial curvature in the presence of a bulk cosmological constant. We find the general solution of such a configuration in the presence of a Gauss-Bonnet term. Two classes of non-trivial bulk solutions are found. The first class is valid only under a fine tuning relation between the Gauss-Bonnet coupling constant and the cosmologica...
متن کاملGauss-Bonnet Brane Cosmology with Radion Stabilization
G.L. Alberghi 2, 3, ∗ and A. Tronconi 3, † Department of Physics, University of Bologna, Via Irnerio 46, 40126 Bologna, Italy. Department of Astronomy, University of Bologna, Italy. I.N.F.N., Sezione di Bologna, Italy. We study cosmology in a five-dimensional brane-world with a stabilizing effective potential for the radion and matter localized on the two branes. We consider the corrections ind...

متن کاملNoether symmetries in Gauss–Bonnet-teleparallel cosmology
A generalized teleparallel cosmological model, [Formula: see text], containing the torsion scalar T and the teleparallel counterpart of the Gauss-Bonnet topological invariant [Formula: see text], is studied in the framework of the Noether symmetry approach. As [Formula: see text] gravity, where [Formula: see text] is the Gauss-Bonnet topological invariant and R is the Ricci curvature scalar, ex...
متن کاملGravitational baryogenesis in Gauss-Bonnet braneworld cosmology
The mechanism of gravitational baryogenesis, based on the CPT -violating gravitational interaction between the derivative of the Ricci scalar curvature and the baryon-number current, is investigated in the context of the Gauss-Bonnet braneworld cosmology. We study the constraints on the fundamental five-dimensional gravity scale, the effective scale of B-violation and the decoupling temperature...
