Abstract
I present two very different uses of the idea of pseudopotentials in the theory of cuprate superconductors. In the first, the ‘chemical pseudopotential’ scheme is used to set up the underlying Hubbard model which is appropriate for these substances; in the second, I show that the conventional multiple-scattering technique for constructing an effective scattering length theory does not converge for the two- dimensional Hubbard model.
