Post-inflationary scalar field phase dynamics

T. Charters, A. Nunes, J. P. Mimoso

We present a brief summary of the results of Charters et al. [1] where a simple model of a massive inflation field ? coupled to another scalar filed ? with interaction term g 2?2?2 for the first stage of preheating, and we give a full description of the dynamics of the ? field modes, including the behaviour of the phase, in terms of the iteration of a simple family of circle maps.
