Physical Review Letters, 2013•APSWe present the first (3+ 1)-dimensional numerical simulations of scalar fields with
nonminimal kinetic terms. As an example, we examine the existence and stability of
preheating in the presence of a Dirac-Born-Infeld inflaton coupled to a canonical matter field.
The simulations represent the full nonlinear theory in the presence of an expanding
universe. We show that parametric resonance in the matter field along with self-resonance in
the inflaton repopulate the universe with matter particles as efficiently as<? format?> in …
