Brane-Bulk energy exchange and agegraphic dark energy

Abstract

We consider the agegraphic models of dark energy in a braneworld scenario with brane-bulk energy exchange. We assume that the adiabatic equation for the dark matter is satisfied while it is violated for the agegraphic dark energy due to the energy exchange between the brane and the bulk. Our study shows that with the brane-bulk interaction, the equation of state parameter of agegraphic dark energy on the brane, $w_D$, can have a transition from normal state where $w_D>-1$ to the phantom regime where $w_D<-1$, while the effective equation of state for dark energy always satisfies $w_D^{\mathrm{eff}}\ge -1$.
