Abstract. We investigate a spinless fermion system on a one dimensional
lattice interacting locally with the optical modes of a quantized
phonon field: the Holstein model. The system is shown to have a
disordered ground state, for small enough coupling, at any density.
This is in contrast to the non quantized phonon case, the static
Holstein model, which at half filling has an ordered ground state for
