Critical dynamics of a model for distortive structural phase transitions
Abstract
Extending the phenomenological law due to Machlup and Onsager, the authors present a model for systems undergoing distortive structural phase transitions. It is then shown that the critical dynamics reduce to that of the kinetic Ising model. In a certain limit, the model can be solved exactly.
