Inflation, brane worlds and quintessence
Apr, 2001Citations per year
Abstract: (Elsevier)
Inflationary cosmology is developed in the second Randall–Sundrum braneworld scenario, where the accelerated expansion arises through potentials that are too steep to drive inflation in conventional cosmology. A relationship between the scalar and tensor perturbation spectra is derived that is independent of both the inflaton potential and the brane tension. It is found that a single field with an inverse power law potential can act as both the inflaton and the quintessence field for suitable values of the brane tension.Note:
