    • Importantly, in both papers the "off diagonal" (i.e., non density density) interaction terms were discussed and in Hubbard's model were shown explicitly to be negligibly small in the specific case of interest to the original author. The term "extended Hubbard model" is often used for a model with only density dependent on site and nearest neighbor interactions U and V. Here we use this terminology in the more general sense, including the off diagonal interactions
