Abstract

In this paper we consider the effect of disorder on the non-dissipative Coulomb drag between two mesoscopic metal rings at zero temperature. Ring 1 has an Aharonov-Bohm flux present which creates a persistent current J0. Ring 2 interacts with ring 1 via the Coulomb potential and a drag current, Jd is produced. We show that this drag current persists with finite disorder in each ring, and that for small disorder, Jd decreases with the square of the disorder amplitude.
