1205.1663 (Pascal M. Vaudrevange et al.)

A Toy Model For Single Field Open Inflation    [PDF]

Pascal M. Vaudrevange, Alexander Westphal
Inflation in an open universe produced by Coleman-De Luccia (CDL) tunneling induces a friction term that is strong enough to allow for successful small-field inflation in models that would otherwise suffer from a severe overshoot problem. In this paper, we present a polynomial scalar potential which allows for a full analysis. This provides a simple model of single-field open inflation on a small-field inflection point after tunneling. We present numerical results and compare them with analytic approximations.
