Abstract:We study a model of fully-packed dimer configurations (or perfect matchings) on a bipartite periodic graph that is two-dimensional but not planar. The graph is obtained from Z 2 via the addition of an extensive number of extra edges that break planarity (but not bipartiteness). We prove that, if the weight λ of the non-planar edges is small enough, the height function scales on large distances to the Gaussian Free Field with a λ-dependent amplitude, that coincides with the anomalous exponent of dimer-dimer cor… Show more
