We study the dynamics of a scalar inflaton field with a symmetric double-well potential and prove rigorously the existence of a limit cycle in its phase space. By using analytical and numerical arguments we show that the limit cycle is stable and give an analytical formula for its period.

Abstract
We study the dynamics of a scalar inflaton field with a symmetric double-well potential and prove rigorously the existence of a limit cycle in its phase space. By using analytical and numerical arguments we show that the limit cycle is stable and give an analytical formula for its period.File in questo prodotto:
