Preheating with Non-Minimal Kinetic Terms
  We present the first 3+1-dimensional numerical simulations of scalar fields
with non-minimal kinetic terms. As an example, we examine the existence and
stability of preheating in the presence of a Dirac-Born-Infeld (DBI) inflaton
coupled to a canonical matter field. The simulations represent the full
non-linear 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 in
traditional preheating.
