Abstract

We study the process of spinodal decomposition in a scalar quantum field theory that is quenched from an equilibrium disordered initial state at Ti>TfT_i > T_f to a final state at Tf0T_f \approx 0. The process of formation and growth of correlated domains is studied in a Hartree approximation. We find an approximate scaling law for the size of the domains ξD(t)tξ0\xi_D(t) \approx \sqrt{t \xi_0} at long times for weakly coupled theories, with ξ0\xi_0 the zero temperature correlation length.
