Physics pair show that Ising model can be used as a universal spin model

(Phys.org)--A pair of physicists has shown that it is possible to transform disparate spin models into different types of just one simple model. In their paper published in the journal Science, Gemma De las Cuevas, with the Max Planck Institute for Quantum Optics and Toby Cubitt, with University College London, offer a proof to show that any spin model can be converted to the relatively simple Ising model. Stephanie Wehner with QuTech, Delft University of Technology offers a Perspectives piece o...
