Parametric Excitation of Edge Waves in the Quantum Hall Effect
arXiv:cond-mat/9601041 · doi:10.1103/PhysRevLett.77.719
Abstract
We consider the process of parametric excitation of gapless edge modes in a Hall bar by an alternating current. We find that such a process can be realized provided both an inter-edge interaction and a constant current are present in the bar. The expected experimental signatures of this phenomenon are discussed.
