We prove that for a class of massless interface models of gradient type on the 2D square lattice an introduction of an arbitrary small pinning self-potential leads to exponential decay of correlation, or, in other words, to creation of mass.
Key words:
Non-Gaussian gradient model, SOS model, pinning, decay of correlations, Helffer-Sjï¿œstrand representation, Brascamp-Lieb inequality.
