# Rapid asymmetric inflation and early cosmology in theories with sub-millimeter dimensions

@article{ArkaniHamed2000RapidAI, title={Rapid asymmetric inflation and early cosmology in theories with sub-millimeter dimensions}, author={Nima Arkani-Hamed and Savas Dimopoulos and Nemanja Kaloper and John March-Russell}, journal={Nuclear Physics}, year={2000}, volume={567}, pages={189-228} }

It was recently pointed out that the fundamental Planck mass could be close to the TeV scale with the observed weakness of gravity at long distances being due the existence of new sub-millimeter spatial dimensions. In this picture the standard model fields are localized to a (3+1)-dimensional wall or ''3-brane''. We show that in such theories there exist attractive models of inflation that occur while the size of the new dimensions are still small. We show that it is easy to produce the…
