Nonlinear Dynamics of Preheating after Multifield Inflation with Nonminimal Couplings
We study the postinflation dynamics of multifield models involving nonminimal couplings using lattice simulations to capture significant nonlinear effects like backreaction and rescattering. We measure the effective equation of state and typical timescales for the onset of thermalization, which coul...
