Damping and the Hartree Ensemble Approximation
arXiv:hep-lat/0010054 · doi:10.1016/S0920-5632(01)00995-1
Abstract
We study a Hartree ensemble approximation for real-time dynamics in the toy model of 1+1 dimensional scalar field theory. Damping behavior seen in numerical simulations is compared with analytical predictions based on perturbation theory in the original (non-Hartree-approximated) model.
