My collaborators and I recently posted a preprintExact mapping from short-ranged harmonic elastic models of spin crossover materials to Ising models with interactions at all length scalesNadeem Natt, Gian Ruzzi, Jace Cruddas, Ross H. McKenzie, Ben J. PowellSpin crossover (SCO) materials are reversible molecular switches found in a wide range of transition metal complexes and metal organic frameworks (MOFs). They exhibit diverse spin state orderings and transitions between them. Here we present an exact mapping from harmonic elastic models to Ising-like models with both a short-range Ising interaction that decays with a power law at large distances and a long-range...
