A PHASE FIELD SYSTEM WITH MEMORY: Stability and Damped Oscillations

摘要

Recently a phenomenological model has been proposed to describe first order phase transitions which take place in the presence of configurational modes which resolve themselves on a slow time scale. This model takes the form of a phase field system with memory. A major feature of this model, as opposed to the classical phase field model, is the possibility of damped oscillations which can appear when considering the stability of steady states as well as in the inter-facial motion which occurs during coarsening.
