Quantum Hall effect in Coulomb drag: Interlayer friction in strong magnetic fields
Quantum Hall effect in Coulomb drag: Interlayer friction in strong magnetic fields
We study the Coulomb drag between two spatially separated electron systems in the quantum Hall regime. At a fixed temperature, the drag is peaked near the transitions between plateaus. The temperature dependence of the drag is a probe of the dynamics of the Hall system in a frequency and wave-vector …
