Anisotropic Power Law Inflation from Rolling Tachyons
arXiv:1105.4455 · doi:10.1142/S0217732312500095
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.
