Abstract
The evolution of a time-dependent Ginzburg-Landau model with a scalar, nonconserved order parameter and Langevin dynamics is studied in the case where the system is initially very cold except for a localized hot region. It is found that for certain values of the system parameters a relatively long-lasting structure appears consisting of a hotter shell enclosing a cold interior. The possible relation of this structure to similar effects which have been hypothesized to occur in He3 is discussed. Implications for other phenomena are briefly mentioned.
