Abstract
We investigate the influence of many-body correlations on Coulomb drag between spatially separated conducting layers of electrons. We show t hat the correlations enhance the drag particularly strongly at low ele ctron densities but cannot be ignored el en for relatively high concen trations. The enhancement of transresistivity is weaker than in simila r electron-hole systems, mostly due to the larger effective mass of ho les.
