Closed Universe in Mirage Cosmology
We study the cosmological evolution of the closed universe on a spherical probe brane moving in the AdSm × S background and the near-horizon background of the dilatonic D-branes. The Friedmann equations describing the evolution of the brane universe, and the effective energy density and pressure simulated on the probe brane due to its motion in the curved background spacetime are obtained and a...
متن کاملMirage Cosmology
A brane universe moving in a curved higher dimensional bulk space is considered. The motion induces a cosmological evolution on the universe brane that is indistinguishable from a similar one induced by matter density on the brane. The phenomenological implications of such an idea are discussed. Various mirage energy densities are found, corresponding to dilute matter driving the cosmological e...
متن کاملBrane Inflation from Mirage Cosmology
We study the cosmological evolution of a D3-brane universe in a type 0 string background. We follow the brane-universe along the radial coordinate of the background and we calculate the energy density which is induced on the brane because of its motion in the bulk. We find that for some typical values of the parameters the brane-universe has an inflationary phase.
متن کاملType 0 Brane Inflation from Mirage Cosmology
We consider a three-dimensional brane-universe moving in a Type 0 String background. The motion induces on the brane a cosmological evolution which, for some range of the parameters, exhibits an inflationary phase.
متن کاملCosmology in a brane-universe
The purpose of this contribution is to present a new approach to extra-dimensions, the “braneworld” scenario, where ordinary matter is trapped in a three-dimensional surface, called ‘brane’, embedded in a higher dimensional space. This idea must be contrasted with the traditional Kaluza-Klein treatment of extra dimensions, where matter fields live everywhere in compact extra dimensions and can ...
