Theory of edge magnetoplasmons in a two-dimensional electron gas
Volkov V. A., Mikhailov S. A.
In a bounded two-dimensional electron gas the spectrum of edge magnetoplasmons is a gap-free spectrum. In the quantum Hall effect regime, the velocity of the "optical"edge magnetoplasmons is quantized. In classical magnetic fields, the results are in quantitative agreement with the experimental data for 2D electrons bound to a liquid-helium surface.
