Description:
Author(s): Richard Easther, Jonathan Frazer, Hiranya V. Peiris, and Layne C. Price We explore whether multifield inflationary models make unambiguous predictions for fundamental cosmological observables. Focusing on N-quadratic inflation, we numerically evaluate the full perturbation equations for models with 2, 3, and O(100) fields, using several distinct methods for specifying t... [Phys. Rev.
