A system of fermions on a one-dimensional lattice, subject to a weak periodic potential whose period is incommensurate with the lattice spacing and satisfies 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 multiples of the potential period.

Abstract

A system of fermions on a one-dimensional lattice, subject to a weak periodic potential whose period is incommensurate with the lattice spacing and satisfies 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 multiples of the potential period.
