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 and for a particular range of values of the scale factor of the brane-universe, the effective energy density is dominated by a term proportional to $\frac{1}{(loga)^{4…

Mirage cosmology of U(1) gauge field on unstable D3 brane universe

An unstable D3-brane universe governed by the DBI action of the tachyon field minimally coupled to a U(1) gauge boson is examined. The cosmological evolution of this coupled system, is further…

AdS/CFT correspondence and the reheating of the brane-universe

We present a mechanism for exit from inflation and reheating using the AdS/CFT correspondence. A cosmological evolution is induced on a probe D3-brane as it moves in a black D-brane background of…

The cosmological slingshot scenario: a stringy early times universe

A cosmological model for the early time universe is proposed. In this model, the universe is a wandering brane moving in a warped throat of a Calabi–Yau space. A nonzero angular momentum induces a…

Brane Cosmology

The aim of these lectures is to give a brief introduction to brane cosmology. After introducing some basic geometrical notions, we discuss the cosmology of a brane universe with matter localized on…

Geometrical tachyon dynamics in the background of a bulk tachyon field

We study the dynamics of a D3-brane moving in the background of a bulk tachyon field of a D3-brane solution of Type-0 string theory. We show that the dynamics on the probe D3-brane can be described…

POWER LAW COSMOLOGICAL SOLUTION DERIVED FROM THE DGP BRANE WITH A BRANE TACHYON FIELD

By studying a tachyon field on the DGP brane model, in order to embed the 4D standard Friedmann equation with a brane tachyon field in the 5D bulk, we present the metric of the 5D space–time. Then,…

We analyze observational constraints on the parameter space of tachyonic inflation with a gaussian potential and discuss some predictions of this scenario. As was shown by Kofman and Linde, it is…
