Abstract

A trial state of the kind suggested by Brandow is used for the nondegenerate periodic Anderson model with arbitrary band filling. An approximate N-parameter minimisation is carried out analytically. A Gutzwiller-type approximation leads to predicting a magnetic instability even in the valence fluctuation regime.
