@article{Piao2003InflationIS, title={Inflation in string-inspired cosmology and suppression of CMB low multipoles}, author={Yunsong Piao and Shinji Tsujikawa and Xinmin Zhang}, journal={Classical and Quantum Gravity}, year={2003}, volume={21}, pages={4455-4461} }

We construct a string-inspired nonsingular cosmological scenario in which an inflaton field is driven up the potential before the graceful exit by employing a low-energy string effective action with an orbifold compactification. This sets up an initial condition for the inflaton to lead to a sufficient number of e-foldings and to generate a nearly scale-invariant primordial density perturbation during slow-roll inflation. Our scenario provides an interesting possibility to explain a suppressed…
