Abstract:

We consider the Cahn-Hilliard equation in one space dimension with scaling parameter $\epsilon$, i.e. $u_t=(W^{′}(u)−\epsilon^2 u_{xx})_{xx}$, where $W$ is a nonconvex potential. In the limit $\epsilon\to 0$, under the assumption that the initial data are energetically well-prepared, we show the convergence to a Stefan problem. The proof is based on variational methods and exploits the gradient flow structure of the Cahn-Hilliard equation.
