Abstract. A system of fermions on a one-dimensional lattice, subject to a periodic
potential whose period is incommensurate with the lattice spacing and
verifies a diophantine condition, is studied.
The Schwinger functions are obtained, and their asymptotic decay for large
distances is exhibited for values of the Fermi momentum which are multiple
of the potential period.
