We study scaling limits and the corresponding large deviation principle of the integrated random walk perturbed by an attractive force toward the origin. In particular we analyse the critical situation that the rate function admits more than one minimiser leading to concentration of measure problems. The integrated random represents interface models with Laplacian interaction for effective interface models (polymers).
