- Title:
- Decay of covariances, uniqueness of ergodic component and scaling limit for a class of ∇ϕ systems with non-convex potential
- Abstract:
- We consider a gradient interface model on the lattice with interaction potential which is a non-convex perturbation of a convex potential. Using a technique which decouples the neighboring vertices into even and odd vertices, we show for a class of non-convex potentials: the uniqueness of ergodic component for ∇ϕ-Gibbs measures, the decay of covariances, the scaling limit and the strict convexity of the surface tension.
