We consider the van der Waals free energy functional in a bounded interval with inhomogeneous Dirichlet boundary conditions
imposing the two stable phases at the endpoints. We compute the asymptotic free energy cost, as the length of the interval
diverges, of shifting the interface from the midpoint. We then discuss the effect of thermal fluctuations by analyzing the
-measure with Dobrushin boundary conditions. In particular, we obtain a non-trivial limit in a suitable scaling in which
the length of the interval diverges and the temperature vanishes. The limiting state is not translation invariant and describes
a localized interface. This result can be seen as the probabilistic counterpart of the variational convergence of the associated
excess free energy. 相似文献
