Dominos and the Gaussian free field. (English) Zbl 1034.82021
Summary: We define a scaling limit of the height function on the domino tiling model (dimer model) on simply connected regions in $$\mathbb{Z}^2$$ and show that it is the “massless free field”, a Gaussian process with independent coefficients when expanded in the eigenbasis of the Laplacian.
