Abstract
I study the evolution of the antiferromagnetic ground state of the half-fil led Hubbard model in the presence of a charge modulation induced by the dim erization of the crystal field, making use of the slave-boson approach. I a lso discuss how the model can be extended to describe the neutral-to-ionic transition which occurs in some organic mixed-stack donor-acceptor crystals .
