Abstract

The ground state of the non-degenerate periodic Anderson model with two electrons/site is studied using a two-parameter version of the variational procedure developed by the author earlier. The energy scale for coherence is V2 / D in the mixed valent regime, and V4 / D3 on the border of the Kondo lattice regime.
