Ground states and magnetic responses of model valence-fluctuation systems
Abstract
Variational ground state wavefunctions are presented and optimized for two model valence-fluctuation systems based on Anderson lattice Hamiltonians in the U approaches infinity limit. Although these wavefunctions are approximate, they are treated in an essentially exact manner. The response of the ground state to a magnetic field is discussed.
