| dc.description | We propose a new approximation-technique to deal with the exact macroscopic integro-differential evolution equations of statistical systems which self-consistently accounts for dissipative effects. Concentrating on one and two point equal-time correlators, we develop the self-consistent method and apply it to a scalar field theory with quartic self-interaction. We derive the effective equations of motion and the corresponding macroscopic effective Hamiltonian. Non-locality in time appears in a natural way necessary to account for entropy generating processes. | |
