Abstract
The Cahn-Hilliard equation is one of the fundamental models for phase separation dynamics in metal alloys. On a qualitative level, it can successfully describe phenomena such as spinodal decomposition and nucleation. Yet, as deterministic partial differential equation it does not account for thermal fluctuations or similar random effects. In this survey we describe some dynamical aspects of a stochastic version of the model due to Cook. These include recent results on spinodal decomposition, as well as a brief discussion of nucleation and its relation to the deterministic attractor structure. In addition, differences between the deterministic and the stochastic dynamics are discussed.
