Topological Inflation with Large Tensor-to-scalar Ratio
arXiv:1404.1680 · doi:10.1088/1475-7516/2014/07/020
Abstract
BICEP2's detection on the primordial B-mode of CMB polarization suggests that inflation occurred around GUT scale, with the tensor-to-scalar ratio r~0.2. Inspired by this discosvery, we study the topological inflation which was driven by a double/single/no well potential. We show that with proper choice of parameters, all these three types of topological inflationary models could be consistent with the constraints from current observations.
