Yang-Baxter Solution of Dimers as a Free-Fermion Six-Vertex Model

Paul A. Pearce, Alessandra Vittorini-Orgeas

It is shown that dimers is Yang-Baxter integrable as a six-vertex model at the free-fermion point with crossing parameter $\lambda =\frac{\pi }{2}$. A one-to-many mapping of vertex onto dimer…
