A Phase Transition between Small and Large Field Models of Inflation
arXiv:0810.4299 · doi:10.1088/0264-9381/26/13/135007
Abstract
We show that models of inflection point inflation exhibit a phase transition from a region in parameter space where they are of large field type to a region where they are of small field type. The phase transition is between a universal behavior, with respect to the initial condition, at the large field region and non-universal behavior at the small field region. The order parameter is the number of e-foldings. We find integer critical exponents at the transition between the two phases.
