Abstract

We present exact results for the periodic Anderson model for finite Hubbard interaction 0 <= U < +infinity on certain restricted domains of the model's phase diagram, in d=1 dimension. Decomposing the Hamiltonian into positive semidefinite terms we find two quantum states to be ground state, an insulating and a metallic one. The ground state energy and several ground state expectation values are calculated.
