The overall fermion determinate is positive definite for the U 0 particle-hole Hubbard model. It is also positive definite for any filling with U 0 as well as for the electron-phonon model in which further potential terms are added to the x-field action.

Here we measure energies in units of the transfer integral t in Eq. (1) so, for example, the bandwidth is 12.
