Mott insulators are materials that would be naively expected to conduct electricity, but nevertheless behave as insulators due to the presence of very strong electronic interactions. In a recent work published in Scientific Reports, graduate student Xu Dou and Prof. Bruno Uchoa have shown that Coulomb impurity lattices on the surface of gapped honeycomb substrates, such as graphene on SiC, can be used to simulate a special class of Mott insulators…
