Anisotropic Power Law Inflation from Rolling Tachyons

preprint2011arXivOpen access

Abstract

We provide an explicit solution representing an anisotropic power law inflation within the framework of rolling tachyon model. This is generated by allowing a non-minimal coupling between the tachyon and the world-volume gauge field on non-BPS D3 brane. We also show that this solution is perturbatively stable.
