GROWTH KINETICS IN THE Φ6N-COMPONENT MODEL: NONCONSERVED ORDER PARAMETER

The dynamics of a system with a nonconserved N-component order parameter described by a Ginzburg–Landau free energy functional containing a sixth order nonlinearity is discussed in the spherical limit. The model displays a richer behavior than the well-studied Φ4 case. In particular it shows interesting properties regarding metastability, a feature which is absent in the spherical Φ4 model.
