Generalized Chaplygin Gas, Accelerated Expansion and Dark Energy-Matter Unification

Abstract

We consider the scenario emerging from the dynamics of a generalized $d$-brane in a $(d+1,1)$ spacetime. The equation of state describing this system is given in terms of the energy density, $\rho$, and pressure, $p$, by the relationship $p=-A/{\rho }^{\alpha }$, where $A$ is a positive constant and $0<\alpha \le 1$. We discuss the conditions under which homogeneity arises and show that this equation of state describes the evolution of a universe evolving from a phase dominated by non-relativistic matter to a phase dominated by a cosmological constant via an intermediate period where the effective equation of state is given by $p=\alpha \rho$.
