Abstract

An electronic current flowing in one conductor can induce a drag current in another spatially separated conductor by means of Coulomb interactions; when these interactions are sufficiently strong the currents become equal and the drag therefore ‘perfect’, as shown here for a bilayer two-dimensional electron system.
