Abstract
A current drag has been observed between a pair of quantum wells in the presence of counterflow. This dissipative current drag effect is temperature dependent (formula presented) There is also a second nondissipative current drag effect that is due to current-induced changes in the correlation energy. This effect does not change the momenta, it only changes the relative velocity and carrier mass. It furthermore remains finite in the limit of zero temperature. In the present work we predict that there will be a current dependent self-energy shift of impurity atoms between two thin conducting sheets that is related to the nondissipative current drag effect.
