Inflaton decay and heavy particle production with negative coupling
We study the decay of the inflaton in a general ${\mathcal{Z}}_{2}\ifmmode\times\else\texttimes\fi{}{\mathcal{Z}}_{2}$ symmetric two scalar theory. Since the dynamics of the system is dominated by states with large occupation numbers which admit a semiclassical description, the decay can be studied by solving the classical equations of motion on the lattice.
