Abstract: there has been substantial progress in recent years in the quantitative understanding of the nonequilibrium time evolution of quantum fields. Important topical applications, in particular in high energy particle physics and cosmology, involve dynamics of quantum fields far away from the ground state or thermal equilibrium.
In non-equilibrium field theory the role of the classical field approximation is much more important since there is no tractable analogue of the 4-dimensional euclidean theory. The classical field approximation should be reliable when the number of field quanta in each relevant field mode is large.
