Department of Physics, The University of Tokyo, Tokyo 113-0033, Japan(Dated: February 1, 2008)We investigate braneworld cosmology based on the D-brane initiated in our previous paper. Thebrane is described by a Born-Infeld action and the gauge field is contained. The higher ordercorrections of an inverse string tension will be addressed. The results obtained by the truncatedargument are altered by the higher order corrections. The equation of state of the gauge field onthe brane is radiation-like…

Quintessential inflation on the brane and the relic gravity wave background

Quintessential inflation describes a scenario in which both inflation and dark energy (quintessence) are described by the same scalar field. In conventional braneworld models of quintessential

Maps of CMB lensing deflection from N-body simulations in Coupled Dark Energy Cosmologies

We produce lensing potential and deflection-angle maps in order to simulate the weak gravitational lensing of the Cosmic Microwave Background (CMB) via ray-tracing through the COupled Dark Energy

The Ekpyrotic Universe



Brane world cosmology

A simple model of the brane-world cosmology has been proposed, which is characterized by four parameters, namely, the bulk cosmological constant, the spatial curvature of the universe, the radiation

Hagedorn inflation of D-branes

We examine the cosmological eects of the Hagedorn phase in models where theobservable universe ispictured asaD-brane. It isshown that,even inthe absence of a cosmological constant, winding modes

Space - like branes

Scalar field theories with appropriate potentials in Minkowski space can have time-dependent classical solutions containing topological defects which correspond to S-branes - i.e. branes all of whose

Brane gases in the early Universe

Over the past decade it has become clear that fundamental strings are not the only fundamental degrees of freedom in string theory. D-branes are also part of the spectrum of fundamental states. In

General brane cosmologies and their global spacetime structure

Starting from a completely general standpoint, we find the most general brane-universe solutions for a 3-brane in a five-dimensional spacetime. The brane can border regions of spacetime with or

Born-infeld cosmologies

We present a model for an inhomogeneous and anisotropic early universe filled with a nonlinear electromagnetic field of Born–Infeld (BI) type. The effects of the BI field are compared with the linear

A Large mass hierarchy from a small extra dimension

We propose a new higher-dimensional mechanism for solving the hierarchy problem. The weak scale is generated from the Planck scale through an exponential hierarchy. However, this exponential arises
