Abstract
We calculate the persistent current of one-dimensional rings of spinle ss fermions with short-range interactions on a lattice with up to 20 s ites, and in the presence of disorder, for various band fillings. We f ind that both disorder and interactions always decrease the persistent current by localizing the electrons. Away from half-filling, the inte raction has a much stronger influence in the presence of disorder than in the pure case.
