Abstract:

I will talk about our recent work (arXiv:1608.01213) in which we calculate the equation of state after inflation and provide an upper bound on the duration before radiation domination by taking the nonlinear dynamics of the fragmented inflaton field into account. For the models considered, I will discuss how our work significantly reduces the uncertainty in inflationary observables.

If time permits I will also discuss our earlier work on baryogenesis from reheating (arXiv:1408.1811) and ongoing work on dynamics of gauge fields after inflation (arXiv:1603.05663).
