【 摘 要 】

We consider the frictional drag in a double-layer system of two-dimensional electrons in the half-filled lowest Landau level. At sufficiently large interlayer separations the drag is dominated by the exchange of acoustic phonons and exhibits a variety of dependencies on temperature and distance between the layers. In all of the regimes, the phonon-mediated drag is found to be strongly enhanced compared to that in zero magnetic field.
