A quantum N-dimer model

Abstract

We study a quantum version of the nn-dimer model from statistical mechanics, based on the formalism from quantum topology developed by Reshetikhin and Turaev (the latter which, in particular, can be used to construct the Jones polynomial of a knot in R3\mathbb{R}^3). We apply this machinery to construct an isotopy invariant polynomial for knotted bipartite ribbon graphs in R3\mathbb{R}^3, giving, in the planar setting, a quantum nn-dimer partition function. As one application, we compute the expected number of loops in the (classical) double dimer model for planar bipartite graphs.
