    Abstract

    We use the Kubo formalism to calculate the transresistivity rho(21) for carriers in coupled quantum wells in a large perpendicular magnetic field B. We find that rho(21) is enhanced by approximately 50-100 times over that of the B = 0 case in the interplateau regions of the integer quantum Hall effect. The presence of both electron-electron interactions and Landau quantization results in (i) a twin-peaked structure of rho(21)(B) in the interplateau regions at low temperatures and (ii) for the chemical potential at the center of a Landau level band, a peaked temperature dependence of rho(21)(T)/T-2.
