Post-inflationary brane cosmology [PDF]
The brane cosmology has invoked new challenges to the usual Big Bang cosmology. In this paper we present a brief account on thermal history of the post-inflationary brane cosmology. We have realized that it is not obvious that the post-inflationary brane

Bottom-up holographic models for cosmology
In this note, we investigate some simple generalizations of a bottom-up holographic approach to cosmology introduced in arXiv:1810.10601 . Our models utilize the Karch/Randall/Takayanagi ansatz for the gravitational dual of a boundary conformal field ...

Non-Abelian brane cosmology [PDF]
We discuss isotropic and homogeneous D-brane-world cosmology with non-Abelian Born-Infeld (NBI) matter on the brane. In the usual Friedmann-Robertson-Walker (FRW) model the scale non-invariant NBI matter gives rise to an equation of state which asymptotes to the string gas equation $p=- /3$ and ensures a start-up of the cosmological expansion with ...

A Note on Thermodynamics and Holography of Moving Giant Gravitons [PDF]
In our previous work (Phys. Rev. D63, 085010, hep-th/0011290), we showed that the brane universe on the giant graviton moving in the near-horizon background of the dilatonic D(6-p)-brane is described by the mirage cosmology.

Cosmological Equations for a Thick Brane [PDF]
Generalized Friedmann equations governing the cosmological evolution inside a thick brane embedded in a five-dimensional Anti-de Sitter spacetime are derived. These equations are written in terms of four-dimensional effective brane quantities obtained by
