Towards inflation in string theory
We investigate the embedding of brane inflation into stable compactifications of string
theory. At first sight a warped compactification geometry seems to produce a naturally flat …

Towards an explicit model of D-brane inflation
We present a detailed analysis of an explicit model of warped D-brane inflation,
incorporating the effects of moduli stabilization. We consider the potential for D3-brane …

Remarks on tachyon driven cosmology
A Sen - Physica Scripta, 2005 - iopscience.iop.org
We begin by reviewing the results on the decay of unstable D-branes in type II string theory,
and the open–closed string duality proposal that arises from these studies. We then apply …

p-adic Inflation
N Barnaby, T Biswas, JM Cline - Journal of High Energy Physics, 2007 - iopscience.iop.org
We construct approximate inflationary solutions rolling away from the unstable maximum of
p-adic string theory, a nonlocal theory with derivatives of all orders. Novel features include …
