TOWARDS A SYSTEMATIC CALCULATION OF THE SCALING FUNCTIONS FOR THE ORDERING KINETICS OF NONCONSERVED FIELDS

A systematic approach to the solution of the time-dependent Ginzburg-Landau equation for a nonconserved field, with random initial conditions appropriate to a quench from the disordered to the ordered phase, is introduced. In leading order, the scaling functions for two-point correlations have the Ohta-Jasnow-Kawasaki form and its generalization to vector fields.
